NEW SEATS!!!CCM 1A Warm Up:

1. Create an equation in one variable whose solution is no solution.

2. Create an equation in one variable which has infinite solutions.

3. Solve x + 2 = x - 2. What do you notice about this problem?

Warm Up:

1. Create an equation in one variable whose solution is no solution. VARIES

2. Create an equation in one variable which has infinite solutions. VARIES

3. Solve x + 2 = x - 2. What do you notice about this problem? x + 2 = x – 2

-x -x 2 ≠ -2False therefore no

solution

Discuss QUIZ if all finished!

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 = – 10 -28 = -28

2x = – 38x = -19

Example 2:

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

Example 3:

Rewrite as Now you solve!
