What is (6x-3) + (8x-14) ?

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
