x in (-oo:+oo)
(1-x)/2-((x-2)/3) = -x/4 // + -x/4
(1-x)/2-((x-2)/3)-(-x/4) = 0
(1-x)/2-((x-2)/3)+(1/4)*x = 0
(1-x)/2+(-1*(x-2))/3+x/4 = 0
(3*4*(1-x))/(2*3*4)+(-1*2*4*(x-2))/(2*3*4)+(2*3*x)/(2*3*4) = 0
3*4*(1-x)-1*2*4*(x-2)+2*3*x = 0
6*x-20*x+28 = 0
28-14*x = 0
(28-14*x)/(2*3*4) = 0
(28-14*x)/(2*3*4) = 0 // * 2*3*4
28-14*x = 0
28-14*x = 0 // - 28
-14*x = -28 // : -14
x = -28/(-14)
x = 2
x = 2
