(2x-3)× (5x+20)= (2x+1)(5x-4)
10x^2+40x-15x-60= 10x^2-8x+5x-4
10x^2-10x^2+25x+8x-5x=-4+60
33x-5x=56
28x=56
x= 56/28
x=2
10x^2+40x-15x-60= 10x^2-8x+5x-4
10x^2-10x^2+25x+8x-5x=-4+60
33x-5x=56
28x=56
x= 56/28
x=2

your answer is here:
(2x-3)/(5x-4)=(2x+1)/(5x+20)
2x-3(5x+20)=2x+1(5x-4)
10x+40x-15x-60=10x-8x+5x-4
35x-60=7x-4
35x-7x=60-4
28x=56
x=56/28
x=2
