Yeah I did that but my whats the correct answer for x? I foiled the numbers then tried to factor but that didn't work.

Cross multiply, then FOIL on both sides. (x  1)(x  2) = (x + 1)(x  3)

thats what i got but then x would have to be x^2  x + 5 = x^2 that would have to be the answer.

Good. Now subtract x^2 from both sides.

0= x + 5 then add x to the other side x= 5

x^2  3x + 2 = x^2  2x  3  x^2 x^2  3x + 2 = 2x  3 + 2x 2 +2x  2  x = 5 x = 5
