x - 15 = - 8 add 15 to both sides: x -15 + 15 = -8 + 15 simplify both sides: x = 7

x + 15 = 54x = 54 - 15 = 39ANSWER: 39
x-10=15 Add 10 to both sides x=25
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
Divide each side by -15 and x = - 6/15.
x - 15 = - 8 add 15 to both sides: x -15 + 15 = -8 + 15 simplify both sides: x = 7
