8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
9x2 + 8x - 1 = (9x - 1)(x + 1)
9x + 4 - x + 8 = 8x + 12
Do you mean what is 8x + 9x (=17x) ?

9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
8x + x = 9x
8x + 9x = x(8 + 9) = x(17) = 17x

9x + 2 = x - 5Subtract 'x' from each side of the equation:8x + 2 = -5Subtract 2 from each side:8x = -7Divide each side by 8 :x = -7/8The solution set is { -7/8 } .
Integral : 9x + 8 = 9(x squared)/2 + 8x Differential : 9x +8 = 9
x = -8
9x - 9 = 36 9x = 45 x = 5
x + 8x = 477 9x = 477 x = 53
