3 What is the opposite of multiplication? What is the opposite of addition? What is the opposite of subtraction? What is the opposite of division? ??Questions?? Division Subtraction Addition Multiplication

4 Multiple Step Equations #1 3 Types : Type 1 : -3x + 10 = 1 Pencils Down Type 2: -3x + 10 + 5x = -2 Type 3: 8x + x + 3 = 10 + 2

5 Type 1 : -3x + 10 = 1 You need to get x xx x all by itself! Adding Subtracting  Get rid of the Adding or Subtracting! - 10 = -3x-9 + 0 -3 MultiplicationDivision  Now get rid of the Multiplication or Division! x = 3 Opposite Do the Opposite!

6 You try : -2x – 12 = 2 Adding Subtracting  Get rid of the Adding or Subtracting! +12 = -2x14 + 0 -2 MultiplicationDivision  Now get rid of the Multiplication or Division! x = -7 Opposite Do the Opposite!

7 Type 2 : -3x + 10 + 5x = -2  Collect Like Terms. Use a Chart! x # -3 5 2x 10 2x + 10 = -2 Subtracting  Get rid of the Adding or Subtracting! Do the Opposite! - 10 2x + 0 = -12 MultiplicationDivision  Now get rid of the Multiplication or Division! Do the Opposite! 2 2 x = -6

8 On your own : -2x + 9 + 6x = 13  Collect Like Terms. Use a Chart! x # -2 6 4x 9 9 4x + 9 = 13 Adding Subtracting  Get rid of the Adding or Subtracting! Do the Opposite! - 9 4x + 0 = 4 MultiplicationDivision  Now get rid of the Multiplication or Division! Do the Opposite! 4 4 x = 1

9 Type 3 : 8x + x + 3 = 10 + 2  Collect Like Terms. Use a Chart! x # 8 1 9x 3 3 9x + 3 = 12 Subtracting  Get rid of the Adding or Subtracting! Do the Opposite! - 3 9x + 0 = 9 MultiplicationDivision  Now get rid of the Multiplication or Division! Do the Opposite! 9 9 x = 1  Do One Side FIRST! 9x + 3  Now do the other side! = 10 + 2
