Question reads: 1 over 1 + (plus) X - (minus) 1 over 3 - (minus) X = (EQUALS) 6 OVER 35
--------------------------
1/(1+x) - 1/(3-x) = 6/35
lcm = 35(1+x)(3-x)
Multiply thru by the lcm to get:
35(3-x) - 35(1+x) = (1+x)(3-x)
105-35x -35 -35x = 3 +2x -x^2
x^2 -72x + 102 = 0
x = [72 +- sqrt(72^2-4*102)]/2
x = [72 +- 69.1086..]/2
x = 1.4456... x = 70.554...
