Solving One-Step Equations with Subtraction


Solving one-step equations is easy with these simple steps.

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

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

In our last example we will again deal with a negative numbers. We solve the problem the exact same way, but we have to make sure that we don't lose the negative. Take a look at this example.

Example 3


solving one-step 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.
