one solution x = [tex]\frac{2}{3}[/tex]

distribute and simplify the right side of the equation.

- 6 - 4x = 8x - 14

subtract 8x from both sides

- 6 - 4x - 8x = - 14

- 6 - 12x = -14

add 6 to both sides

- 12x = - 14 + 6

- 12x = - 8

divide both sides by - 12

x = [tex]\frac{-8}{- 12}[/tex] = [tex]\frac{2}{3}[/tex]
