7th Grade - Simplifying Linear Expression

Today we spent more time expanding and simplifying linear expressions using the steps below:
1. Remove parentheses by applying distributive property
2. Collect like terms
3. Add or subtract integers to simplify expressions

* Remember that you cannot add or subtract unlike terms

Below is a video that might help by reminding you of today's lesson on distributive property and combining like terms.
