# Solving One-Step Linear Equations: Subtraction

Algebra might seem a little difficult at first, but we can use all kinds of interesting tricks and rules to make this much easier. One of the most useful tricks involves subtraction. This one-step trick will have us solving equations in no time!

## Subtracting is as easy as adding

We can solve many linear equations by simply doing the *opposite *of the listed operation*. *So instead of subtracting, we instead *add* numbers to both sides of the equation. This is known as the "inverse operation."

Here''s an example:

So what is x?

All we need to do here is add 9 to both sides since the opposite of subtraction is addition. The goal is to clear away the 9 and get x by itself.

The +9 on the left side of the equation "cancels out" the -9, leaving us with zero.
