**Warm-ups -6 +4x -4x + 11 + 2x = -3 x – 2(3 – 2x) = 19 x - 6 + 4x = 19**

Solve for x: -6 +4x 1.) -4x x = -3 2.) x – 2(3 – 2x) = 19 x # x x = 19 x # -2x + 11 = -3 1 -6 -4 11 5x – 6 = 19 - 11 -11 4 2 +6 +6 -2x 11 -2x + 0 = -14 5x -6 5x + 0 = 25 -2 -2 5 5 x = 7 x = 5 3 3.) - x = 9 4 - 3 4 -4● x = 9 ●-4 Warm-ups Mr. Steelman 1.) 2.) 3x = -36 3 3 x = -12

**Worksheet Multi-step Equations #2**

Answers to Homework Worksheet Multi-step Equations #2 2.) x = 3 3.) y = -4 4.) x = -2 5.) x = 1 6.) x = 1 7.) n = -2 9.) y = -1 10.) y = 3 11.) y = 1 12.) y = 9

**CA Standards: Objectives: Agenda 1.) Warm-ups**

4.0: Students simplify expressions before solving linear equations in one variable. Objectives: (1) Students simplify expressions use inverse operations to solve equations. Agenda 1.) Warm-ups 2.) Lesson Multi-Step Equations #3 ppt. 3.) Assignment-(Group Work)

**Multiple Step Equations #3**

1 type: Type 1: 4x + 9 = 2x – 1 4x + 9

5
**Type 1: 4x + 9 = 2x -1 -2x -2x 2x + 9 = -1 - 9 -9 2x +0 = -10 2 2 x =**

Move the variable on the right side of the equal sign. -2x -2x Do the Opposite! 2x Add or subtract the number on the left side of the equal sign. + 9 = -1 - 9 -9 Do the Opposite! 2x +0 = -10 Multiply or Divide to isolate the variable. 2 2 Do the Opposite! x = – 5

6
**You Try: 3x + 7 = 5x -7 -5x -5x -2x + 7 = -7 - 7 -7 -2x +0 = -14 -2 -2**

Move the variable on the right side of the equal sign. -5x -5x Do the Opposite! -2x + 7 = -7 Add or subtract the number on the left side of the equal sign. - 7 -7 Do the Opposite! -2x +0 = -14 Multiply or Divide to isolate the variable. -2 -2 Do the Opposite! x = 7

7
**Try Again: -4x – 8 = 3x +6 -3x -3x -7x – 8 = +6 +8 +8 -7x +0 = 14 -7**

Move the variable on the right side of the equal sign. -3x -3x Do the Opposite! -7x – 8 = +6 Add or subtract the number on the left side of the equal sign. +8 +8 Do the Opposite! -7x +0 = 14 Multiply or Divide to isolate the variable. -7 -7 Do the Opposite! x = -2
