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
