Objectives: Students will be able to: Solve equations using proportions. Create equations with one variable and use them to solve multi-step problems.

Algebraic Proportions: Steps: Cross multiply Distribute Combine like terms Add or subtract to isolate the variable Multiply or divide to isolate the variable

Example 1: 7(x + 4) = 5(x – 2) 7x + 28 = 5x – 10 -5x = -5x 2x + 28 = – = -28 2x = – 38 x = -19

Example 2: 5(x+2) = 14(x) Now you solve!

Example 3: Rewrite as Now you solve!
