x in (-oo:+oo)
3*(x-13)-(x/3) = x/2 // - x/2
3*(x-13)-(x/3)-(x/2) = 0
3*(x-13)-x/3-x/2 = 0
(2*3^2*(x-13))/(2*3)+(2*(-x))/(2*3)+(3*(-x))/(2*3) = 0
2*3^2*(x-13)+2*(-x)+3*(-x) = 0
16*x-3*x-234 = 0
13*x-234 = 0
(13*x-234)/(2*3) = 0
(13*x-234)/(2*3) = 0 // * 2*3
13*x-234 = 0
13*x-234 = 0 // + 234
13*x = 234 // : 13
x = 234/13
x = 18
