2) -8(-8x - 6) = -6x – 22

Answers

Answer:

x = -1

Step-by-step explanation:

-8(-8x - 6) = -6x - 22          {Use distributive property}

(-8) * (-8x)  - 6 *(-8) = -6x - 22    

64x +  48 = -6x -22  {Add 6x to both sides}

64x + 6x + 48 = -22         {Subtract 48 from both sides}

         70x     = -22 -48

              70x = -70            {Divide both sides by 70}

                  x = -70/70

x = -1
