x in (-oo:+oo)
(X-2)/6 = (x-1)/12 // - (x-1)/12
(X-2)/6-((x-1)/12) = 0
(X-2)/6+(-1*(x-1))/12 = 0
(12*(X-2))/(6*12)+(-1*6*(x-1))/(6*12) = 0
12*(X-2)-1*6*(x-1) = 0
12*X-6*x-18 = 0
(12*X-6*x-18)/(6*12) = 0
(12*X-6*x-18)/(6*12) = 0 // * 6*12
12*X-6*x-18 = 0
12*X-6*x-18 = 0 // - 12*X-18
-6*x = -(12*X-18) // : -6
x = (-(12*X-18))/(-6)
x = (18-(12*X))/(-6)
x = (18-(12*X))/(-6)
