Solution for 3=(3u+7)/6+(u-2)/3 equation: 


u in (-oo:+oo)

3 = (3*u+7)/6+(u-2)/3 // - (3*u+7)/6+(u-2)/3

3-((3*u+7)/6)-((u-2)/3) = 0

(-1*(3*u+7))/6+(-1*(u-2))/3+3 = 0

(-1*3*(3*u+7))/(3*6)+(-1*6*(u-2))/(3*6)+(6*3^2)/(3*6) = 0

6*3^2-1*3*(3*u+7)-1*6*(u-2) = 0

54-15*u-9 = 0

45-15*u = 0

(45-15*u)/(3*6) = 0

(45-15*u)/(3*6) = 0 // * 3*6

45-15*u = 0

45-15*u = 0 // - 45

-15*u = -45 // : -15

u = -45/(-15)

u = 3

u = 3
