Solution for (2x)/(x-5)=(3x)/(x-2)-2/3 equation:


D( x )

x-5 = 0

x-2 = 0

x-5 = 0

x-5 = 0

x-5 = 0 // + 5

x = 5

x-2 = 0

x-2 = 0

x-2 = 0 // + 2

x = 2

x in (-oo:2) U (2:5) U (5:+oo)

(2*x)/(x-5) = (3*x)/(x-2)-(2/3) // - (3*x)/(x-2)-(2/3)

(2*x)/(x-5)-((3*x)/(x-2))+2/3 = 0

(2*x)/(x-5)-3*x*(x-2)^-1+2/3 = 0

(2*x)/(x-5)+(-3*x)/(x-2)+2/3 = 0

(2*3*x*(x-2))/(3*(x-5)*(x-2))+(-3*3*x*(x-5))/(3*(x-5)*(x-2))+(2*(x-5)*(x-2))/(3*(x-5)*(x-2)) = 0

2*3*x*(x-2)-3*3*x*(x-5)+2*(x-5)*(x-2) = 0

2*x^2-3*x^2+33*x-14*x+20 = 0

19*x-x^2+20 = 0

19*x-x^2+20 = 0

19*x-x^2+20 = 0

DELTA = 19^2-(-1*4*20)

DELTA = 441

DELTA > 0

x = (441^(1/2)-19)/(-1*2) or x = (-441^(1/2)-19)/(-1*2)

x = -1 or x = 20

(x+1)*(x-20) = 0

((x+1)*(x-20))/(3*(x-5)*(x-2)) = 0

((x+1)*(x-20))/(3*(x-5)*(x-2)) = 0 // * 3*(x-5)*(x-2)

(x+1)*(x-20) = 0

( x+1 )

x+1 = 0 // - 1

x = -1

( x-20 )

x-20 = 0 // + 20

x = 20

x in { -1, 20 }
