So we're trying to solve for x. To do this we need to balance the equation. -121 -4x = 39 + 6x Get x on one side; add 4x to both sides. -121 = 39 + 10x Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs). -160 = 10x Divide both sides by 10. x = -16. Hope this helps!
