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

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

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

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
