Solution for ((4x)/(x-2))-4=((x-20)/(x-2)) equation: 


D( x )

x-2 = 0

x-2 = 0

x-2 = 0

x-2 = 0 // + 2

x = 2

x in (-oo:2) U (2:+oo)

(4*x)/(x-2)-4 = (x-20)/(x-2) // - (x-20)/(x-2)

(4*x)/(x-2)-((x-20)/(x-2))-4 = 0

(4*x)/(x-2)+(-1*(x-20))/(x-2)-4 = 0

(4*x)/(x-2)+(-1*(x-20))/(x-2)+(-4*(x-2))/(x-2) = 0

4*x-1*(x-20)-4*(x-2) = 0

3*x-4*x+8+20 = 0

28-x = 0

(28-x)/(x-2) = 0

(28-x)/(x-2) = 0 // * x-2

28-x = 0

28-x = 0 // - 28

-x = -28 // * -1

x = 28

x = 28
