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!
