x in (-oo:+oo)
(x+2)/4-((x-3)/3) = 5/12 // - 5/12
(x+2)/4-((x-3)/3)-(5/12) = 0
(x+2)/4-((x-3)/3)-5/12 = 0
(x+2)/4+(-1*(x-3))/3-5/12 = 0
(3*12*(x+2))/(3*4*12)+(-1*4*12*(x-3))/(3*4*12)+(-5*3*4)/(3*4*12) = 0
3*12*(x+2)-1*4*12*(x-3)-5*3*4 = 0
216-12*x-60 = 0
156-12*x = 0
(156-12*x)/(3*4*12) = 0
(156-12*x)/(3*4*12) = 0 // * 3*4*12
156-12*x = 0
156-12*x = 0 // - 156
-12*x = -156 // : -12
x = -156/(-12)
x = 13
x = 13
