Solution for (3)/(4n-7)=(2)/(2n-5) equation: 


D( n )

4*n-7 = 0

2*n-5 = 0

4*n-7 = 0

4*n-7 = 0

4*n-7 = 0 // + 7

4*n = 7 // : 4

n = 7/4

2*n-5 = 0

2*n-5 = 0

2*n-5 = 0 // + 5

2*n = 5 // : 2

n = 5/2

n in (-oo:7/4) U (7/4:5/2) U (5/2:+oo)

3/(4*n-7) = 2/(2*n-5) // - 2/(2*n-5)

3/(4*n-7)-(2/(2*n-5)) = 0

3/(4*n-7)-2*(2*n-5)^-1 = 0

3/(4*n-7)-2/(2*n-5) = 0

(3*(2*n-5))/((4*n-7)*(2*n-5))+(-2*(4*n-7))/((4*n-7)*(2*n-5)) = 0

3*(2*n-5)-2*(4*n-7) = 0

-2*n-1 = 0

(-2*n-1)/((4*n-7)*(2*n-5)) = 0

(-2*n-1)/((4*n-7)*(2*n-5)) = 0 // * (4*n-7)*(2*n-5)

-2*n-1 = 0

-2*n-1 = 0 // + 1

-2*n = 1 // : -2

n = 1/(-2)

n = -1/2

n = -1/2
