Solving Equations Using Addition and Subtraction

When it comes to solving equations, the addition and subtraction properties play a crucial role. By adding or subtracting the same quantity from both sides of an equation, we can create equivalent equations with easily identifiable solutions. Let’s dive into the steps of using the addition-subtraction property to solve equations.

Step 1: Identify the equation and the variable you want to solve for. For example, consider the equation:

x + 7 = 15

Step 2: Determine whether you need to add or subtract to isolate the variable on one side of the equation. In the given equation, we need to subtract 7 from both sides to isolate the variable x.

x + 7 – 7 = 15 – 7

Step 3: Simplify both sides of the equation by performing the addition or subtraction. In this case:

x = 8

So, the solution to the equation x + 7 = 15 is x = 8. We have successfully used the addition-subtraction property to find the value of x.

To further illustrate the addition-subtraction property, let’s consider another example:

2y – 5 = 11

In this case, we need to add 5 to both sides of the equation to isolate the variable y. After simplifying, we find:

2y = 16

Dividing both sides of the equation by 2, we find that y = 8. The addition-subtraction property allows us to solve equations efficiently by manipulating the equation to isolate the variable of interest.

Example table:

Now that we have mastered the addition-subtraction property, let’s move on to exploring other equation-solving techniques in the upcoming sections.

Solving Equations Using Division

In mathematics, the division property is a valuable tool for solving equations. By dividing both sides of an equation by the same nonzero quantity, we can simplify the equation and find the solution. Let’s explore this method further.

When solving equations using the division property, the goal is to isolate the variable on one side of the equation. By dividing both sides of the equation by the same nonzero number, we create equivalent equations that maintain the equality.

Example:

Consider the equation 5x = 20. To solve for x, we can divide both sides of the equation by 5, as follows:

• 5x/5 = 20/5
• x = 4

The division property allows us to simplify the equation and find its solution efficiently. However, it’s important to note that division can only be performed when the divisor is nonzero. Dividing by zero is undefined and does not yield a valid solution.

Applying the Division Property in Practice

Now that we understand the division property, let’s apply it to a real-life problem:

Problem: You have a cake that is divided into 8 equal slices. How many slices will each person receive if there are 24 people?

To solve this problem, we can set up the following equation: 8x = 24, where x represents the number of slices each person will receive.

By applying the division property, we can divide both sides of the equation by 8:

• 8x/8 = 24/8
• x = 3

Therefore, each person will receive 3 slices of cake.

The division property is a fundamental concept in equation solving and plays a crucial role in various mathematical applications. By understanding and applying this property, we can confidently solve equations involving division and find solutions efficiently.

Solving Equations Using Multiplication

When it comes to solving equations, the multiplication property is a valuable tool in our arsenal. By multiplying both sides of an equation by the same nonzero quantity, we can generate equivalent equations that have the same solution.

Let’s take a look at an example:

x – 5 = 10

To solve this equation, we can use the multiplication property to isolate the variable x. We want to get rid of the constant term (-5) on the left side of the equation, so we can multiply both sides by a suitable number that will cancel it out. Let’s choose 2 as our multiplier:

2(x – 5) = 2(10)

When we distribute the 2 on the left side, we get:

2x – 10 = 20

Now, we can simplify the equation by combining like terms:

2x = 30

Finally, to find the value of x, we divide both sides of the equation by 2:

x = 15

Thus, the solution to the equation x – 5 = 10 is x = 15.

By utilizing the multiplication property, we were able to solve the equation and find the value of x. Remember, when applying this property, it’s crucial to consider the entire equation and perform the same operation on both sides to maintain the equation’s equality.

Further Solutions of Equations

Now that we have learned various equation-solving techniques, we can apply them to solve more complex equations. In this section, we will explore the order of operations, simplification rules, and steps for solving first-degree equations. Let’s dive in!

Let’s see an example:

Solve the equation: 3x + 6 = 15 – 2x

Simplification Rules

When solving equations, it’s important to simplify both sides of the equation by applying simplification rules. Here are some common simplification rules:

1. Combine like terms by adding or subtracting them.
2. Move terms to the opposite side of the equation by adding or subtracting them.
3. Multiply or divide both sides of the equation by the same nonzero quantity.

Let’s apply these simplification rules to solve another equation:

Solve the equation: 2(3x – 4) = 10

By following these equation-solving techniques and simplification rules, we can confidently solve more complex equations. Practice applying these concepts to gain proficiency in solving a variety of mathematical problems.

Let’s start by writing the equation to represent the problem. We can rewrite “three quarters of a number” as “3/4 times the number.” So, the equation becomes:

3/4 * x = 4

Now, to solve for ‘x,’ we must isolate it on one side of the equation. We can do this by using the techniques discussed, such as addition, subtraction, multiplication, and division properties.

Let’s begin by multiplying both sides of the equation by the reciprocal of 3/4, which is 4/3. By doing so, we eliminate the fraction and simplify the equation:

4/3 * (3/4 * x) = 4/3 * 4

By simplifying, we get:

x = 16/3

Therefore, three quarters of 4 is equal to 16/3.

To provide further clarity, let’s visualize the step-by-step solution in a table:
