  • Given   4(-6x-3) + 24 = -72x + 132
  • Distributived Property  -24x -12 + 24 = -72x + 132

                        you multiply 4 to -6x and -3

  • Combine Like terms  -96x + 12 = 132

              you combined the one that has the same variable and no variable number like

                     (-72x )+ (-24x) = -96x

                    (-12) + 24 = 12

  • Subtraction Property of Equality   -96x = 120

        subtract 12 on both sides, like this -96 + 12-12 = 132-12  then you've got -96x = 120

  • Division Property of Equality   x = -1.25

          you divide -96, like this -96x/-96 = 120/-96 , so you will got the x = -1.25
