(x+8)/(3x-5) = (x-8)/(x+5)
(x+8)(x+5) = (x-8)(3x-5)
x²+5x+8x+40 = 3x²-24x-5x+40
3x²-x²-24x-5x-5x-8x = 40-40
2x²-42x = 0
x²-21x = 0
x(x-21) = 0
so,
x = 0 or x-21 = 0
x = 0 or x = 21
(x+8)(x+5) = (x-8)(3x-5)
x²+5x+8x+40 = 3x²-24x-5x+40
3x²-x²-24x-5x-5x-8x = 40-40
2x²-42x = 0
x²-21x = 0
x(x-21) = 0
so,
x = 0 or x-21 = 0
x = 0 or x = 21

(x+8)(x+5)=(x-8)(3x-5)
x^2+13x+40=3x^2-29x+40
2x^2-42x=0
2x(x-12)=0
x=0,. x=12
i hope this will help you
