Solve for x

Solve 6x + 7 - (2x - 7) = 0  for x.

---

​6x + 7 - (2x - 7) = 0
6x + 7 - 2x + 7 = 0   {distributed negative sign through the parentheses}
4x + 14 = 0   {combined like terms}
4x = -14  {subtracted 14 from each side}
x = -14/4   {divided each side by 4}
x = -7/2   {reduced}
or
x = -3.5  {wrote in decimal form}
