Question 420382
Solve the following equation for x


(x - 4)/(x + 6) = (x + 5)/(x + 2)
(x - 4)(x + 2) = (x + 6)(x + 5) {cross-multiplied...it was a proportion}
x^2 - 2x - 8 = x^2 + 11x + 30 {used foil method}
-2x - 8 = 11x + 30 {subtracted x^2 from both sides}
-8 = 13x + 30 {added 2x to both sides}
13x = -38 {subtracted 30 from both sides}
x = -38/13 {divided both sides by 13}
