Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
"x" can not be: 1/2 and -1/2
(7)/(2x+1) - (8x)/(2x-1) = -4
((7)(2x+1)(2x-1))/(2x+1) - ((8x)(2x+1)(2x-1))/(2x-1) = (-4)(2x-1)(2x+1)
(7)(2x-1) - (8x)(2x+1) = (-4)(2x-1)(2x+1)
14x - 7 - 16x^2 - 8x = -16x^2 + 4
6x = 11
x = 11/6
