x in (-oo:+oo)
(1/2)*(3*x+2)-((1/5)*(x+6)) = 5 // - 5
(1/2)*(3*x+2)-((1/5)*(x+6))-5 = 0
(1/2)*(3*x+2)+(-1/5)*(x+6)-5 = 0
1/2*(3*x+2)-1/5*(x+6)-5 = 0
1/2*(3*x+2)-1/5*(x+6)-5 = 0
13/10*x-5-1/5 = 0
13/10*x-26/5 = 0
13/10*x-26/5 = 0
13/10*x-26/5 = 0 // + 26/5
13/10*x = 26/5 // : 13/10
x = 26/5/13/10
x = 4
x = 4
