Solution for 2/(8-d)=5/(3d)-7/(8-d) equation: 


D( d )

3*d = 0

8-d = 0

3*d = 0

3*d = 0

3*d = 0 // : 3

d = 0

8-d = 0

8-d = 0

8-d = 0 // - 8

-d = -8 // * -1

d = 8

d in (-oo:0) U (0:8) U (8:+oo)

2/(8-d) = 5/(3*d)-(7/(8-d)) // - 5/(3*d)-(7/(8-d))

2/(8-d)+7/(8-d)-(5/(3*d)) = 0

2/(8-d)+7/(8-d)+(-5/3)*d^-1 = 0

2/(8-d)+7/(8-d)-5/(3*d) = 0

(2*3*d)/(3*d*(8-d))+(3*7*d)/(3*d*(8-d))+(-5*(8-d))/(3*d*(8-d)) = 0

2*3*d-5*(8-d)+3*7*d = 0

27*d+5*d-40 = 0

32*d-40 = 0

(32*d-40)/(3*d*(8-d)) = 0

(32*d-40)/(3*d*(8-d)) = 0 // * 3*d*(8-d)

32*d-40 = 0

32*d-40 = 0 // + 40

32*d = 40 // : 32

d = 40/32

d = 5/4

d = 5/4
