8[7 - (6x - 6)] + 6x  =  0          Distribute the   -1   to each term in   (6x - 6)  .

 

8[7 - 6x + 6] + 6x  =  0           Distribute the   8     to each term in   [7 - 6x + 6]  .

 

56 - 48x + 48 + 6x  =  0         Combine like terms.

 

104 - 42x  =  0                       Subtract   104  from both sides of the equation.

 

- 42x  =  - 104                        Divide both sides of the equation by   -42  .

 

x  =  52 / 21

x  ≈  2.476
