Solution for 15/y=12/(y-2) equation: 


D( y )

y = 0

y-2 = 0

y = 0

y = 0

y-2 = 0

y-2 = 0

y-2 = 0 // + 2

y = 2

y in (-oo:0) U (0:2) U (2:+oo)

15/y = 12/(y-2) // - 12/(y-2)

15/y-(12/(y-2)) = 0

15/y-12*(y-2)^-1 = 0

15/y-12/(y-2) = 0

(-12*y)/(y*(y-2))+(15*(y-2))/(y*(y-2)) = 0

15*(y-2)-12*y = 0

3*y-30 = 0

(3*y-30)/(y*(y-2)) = 0

(3*y-30)/(y*(y-2)) = 0 // * y*(y-2)

3*y-30 = 0

3*y-30 = 0 // + 30

3*y = 30 // : 3

y = 30/3

y = 10

y = 10
