5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
Do you mean: 5x + 9 - 7x + 6 = x - 18 If so, you can solve this question at this manner: -2x + 15 = x - 18 3x = -3 x = -1

How do you add 2x plus 3y equals 18 in 5x-y equals 11
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
Do you mean: 5x + 9 - 7x + 6 = x - 18 If so, you can solve this question at this manner: -2x + 15 = x - 18 3x = -3 x = -1
