Like terms are terms that can be combined with addition or subtraction. They are either the same variable or are constants.

Like Terms

​

Unlike terms are just terms that connot be combined. You cannot combine an X and a Y

When you combine like terms it is called simplifying your expression. You must simplify before you can solve.

Sometimes you may need to Distribute!​
