Answer:

x = -9

Explanation:

Distribute the -7 to (x + 9) and distribute 9 to (x - 5), creating the equation, -7x - 63 = 9x - 45 -14x. Then you add the like terms, 9x - 14x, which equals -5x. So the equation is now -7x - 63 = -5x -45. Add the -5 to both sides which makes -2x -63 = -45. Then add the -63 to both sides, which equals 18, then divide that by -2 and you get -9 as your answer.
