2X + 25 = 7X subtract 2X from each side 25 = 5X divide both sides by 5 5 = X
it equals 13X.
2x + 5 = 25 2x = 20x = 10

9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
2X + 25 = 7X subtract 2X from each side 25 = 5X divide both sides by 5 5 = X
it equals 13X.
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
