Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
3 + 6x + -8x = -14 + 8x + -8x
Combine like terms: 6x + -8x = -2x
3 + -2x = -14 + 8x + -8x
Combine like terms: 8x + -8x = 0
3 + -2x = -14 + 0
3 + -2x = -14
Add '-3' to each side of the equation.
3 + -3 + -2x = -14 + -3
Combine like terms: 3 + -3 = 0
0 + -2x = -14 + -3
-2x = -14 + -3
Combine like terms: -14 + -3 = -17
-2x = -17
Divide each side by '-2'.
x = 8.5
