I dont know how to solve xDivided line x-1 equals 2x+10 divided line x+11
x = 2x + 10
---- = ------------
x-1 = x+11
Cross multiply
x(x + 11) = (2x +10)(x-1)
x^2 + 11 x = 2x^2 + 10x - 2x - 10
x^2 + 11 x - 2x^2 - 10x + 2x + 10 = 0
-x^2 + 3x + 10 = 0
x^2 - 3x - 10 = 0
x^2 - 5x + 2x - 10 = 0
x(x - 5) +2(x - 5) = 0
(x + 2)(x - 5) = 0
x= -2, 5
