4. Warm ups:

5. Example #1: Solving by Substitution Substitution Method: 1.One equation is solved for one variable in terms of the other. 2.This expression is substituted for the variable in the other equation.

6. Guided Practice Solving by Substitution

7. Example #2: Test Practice Lancaster Woodworkers Furniture Store builds two types of wooden outdoor chairs. A rocking chair sells for $265 and an Adirondack chair with footstool sells for $320. The books show that last month the business earned $13,930 for the 48 outdoor chairs sold. How many rocking chairs were sold?

8. Guided Practice #2: Test Practice Dante spent $11.25 on 3 new and 4 old comic books, and Samantha spent $15.75 on 10 old and 3 new ones. If comics of one type are sold at the same price, what is the price in dollars of a new comic book?
