Faceing math lesson 7 multi-step equations with variables on both sides

7) 2x + 2 = 10x + 4

   -8x = -2

   x  = 1/4

8) -x - 5 = 2x + 10

   -3x = 15

   x = -5

9) x + 3 = -5x

   6x = -3

   x = -1/2

10) -x - 10 = -3x - 8

     2x = 2

     x = 1

11) 1/2x = -3/2x + 4

    2x = 4

    x = 1/2

12) 3x -8 = -8 + 3x

     0 = 0

Hope this helps! ;)

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
