Solution for 3-(x+1)/(x+2)=(11x-2)/(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)

3-((x+1)/(x+2)) = (11*x-2)/(x+2) // - (11*x-2)/(x+2)

3-((x+1)/(x+2))-((11*x-2)/(x+2)) = 0

(-1*(x+1))/(x+2)+(-1*(11*x-2))/(x+2)+3 = 0

(-1*(x+1))/(x+2)+(-1*(11*x-2))/(x+2)+(3*(x+2))/(x+2) = 0

3*(x+2)-1*(x+1)-1*(11*x-2) = 0

3*x-12*x+1+6 = 0

7-9*x = 0

(7-9*x)/(x+2) = 0

(7-9*x)/(x+2) = 0 // * x+2

7-9*x = 0

7-9*x = 0 // - 7

-9*x = -7 // : -9

x = -7/(-9)

x = 7/9

x = 7/9
