9(3x - 16) + 15 = 6x - 24 First distribute 9 to 3x and -16. 27x - 144 + 15 = 6x - 24 Combine like terms. (-144 + 15) 27x - 129 = 6x - 24 Get the variable, x, on one side of the equation. You can do this by subtracting 6x from both sides. 21x - 129 = -24 Add 129 to both sides to isolate x. 21x = 105 Divide 21 off of both sides to find the value of x. x = 5 You can plug x into the equation to check your answer. 9(3 x 5 - 16) + 15 = 6(5) - 24 6 = 6
