Solving Equations with Combining Like Terms

Solving Equations with Combining Like Terms

by Casey Jackson

Term - one piece of an expression

If expressions are sentences,

terms are the individual words.

The example shown has 3 terms.

The sign before each term tells you if the term is positive or negative.

​Write this down in your notebook!!!

Like Terms - terms that look alike!

Look for terms with constants, or terms with the same variable

We can combine like terms to simplify long expressions.
