Solving One-Step Equations with Subtraction

We will use the same methods to solve subtraction equations as we did with equations that were addition problems.

Except this time, can you guess what the opposite mathematical operation is going to be? You got it - Addition! We are going to add in order to get the variable by itself!

Here are a few examples!


Example 1: Subtraction Equations

Solving one-step subtraction equations


In example 2 we will see what happens when you have a negative number as your answer. Don't forget your integer rules!

Example 2: Working with Negative Numbers

Solving subtraction equations

Are you starting to catch on? Yes! For subtraction equations, we must add in order to solve the equation. I bet you are now ready to solve multiplication equations.
