Assume your problem is:
+ = 1 +
Factor
+ = 1 +
Multiply by common denominator; 2(x+1)(x-1), results:
2x + 2(2(x-1)) = 2(x+1)(x-1) + (x+1)
:
2x + 4x - 4 = 2(x^2-1) + (x + 1)
:
6x - 4 = 2x^2 - 2 + x + 1
:
6x - 4 = 2x^2 + x - 1
:
0 = 2x^2 + x - 6x - 1 + 4
:
0 = 2x^2 - 5x + 3
Factor this to
(2x-3)(x-1) = 0
two solutions:
x = 1
and
2x = 3
x =
x = 1.5
;
The 1st answer, x=1 cannot be a solution, division by 0, therefore;
x = 1.5 is the only solution
