multiply both sides by (x-3)(x+1) so that, with cancelling, we can cancel the fractions to leave:
(x+1)(x-2) = (x-3)(x-1)
3x = 5
x = 5/3

when you know that if a/b = c/d then is a*c = b*d.
Applying this here we get:
(x-2)(x+1)= (x-3)(x-1); now we 'distribute':
x²+x-2x-2 = x²-x-3x+3
or -x -2 = -4x +3 (the x² is gone because it was at the both sides)
bringing to the left hand side:
3x-5=0
this gives x=5/3 as solution.
