(2x+3)/(x-4)-(2x-8)/(2x+1)=1\ \ \ |the\ domain\ D:x\\eq4\ and\ x\\eq-(1)/(2)\\\\((2x+3)(2x+1))/((x-4)(2x+1))-((2x-8)(x-4))/((2x+1)(x-4))-1=0\\\\(4x^2+2x+6x+3)/(2x^2+x-8x-4)-(2x^2-8x-8x+32)/(2x^2+x-8x-4)-(2x^2+x-8x-4)/(2x^2+x-8x-4)=0\\\\(4x^2+8x+3)/(2x^2-7x-4)-(2x^2-16x+32)/(2x^2-7x-4)-(2x^2-7x-4)/(2x^2-7x-4)=0\\\\(4x^2+8x+3-2x^2+16x-32-2x^2+7x+4)/(2x^2-7x-4)=0\\\\(31x-25)/(2x^2-7x-4)=0\iff31x-25=0\\\\31x=25\\\\\boxed{x=(25)/(31)}
