This is an equation that needs to be balanced to solve for x. -39 -3x = 57 + 5x Add 3x to each side to get x on one side. -39 = 57 + 8x Subtract 57 from both sides to get 8x by itself. (Remember when subtracting a negative by a negative, those numbers combine) -96 = 8x Divide by 8 to get x. x = -12 I hope this helps!
