x in (-oo:+oo)
(2*x-1)/6+(3*x+6)/8 = (1-(4*x))/12 // - (1-(4*x))/12
(2*x-1)/6+(3*x+6)/8-((1-(4*x))/12) = 0
(2*x-1)/6+(3*x+6)/8-((1-4*x)/12) = 0
(2*x-1)/6+(3*x+6)/8+(-1*(1-4*x))/12 = 0
(8*12*(2*x-1))/(6*8*12)+(6*12*(3*x+6))/(6*8*12)+(-1*6*8*(1-4*x))/(6*8*12) = 0
8*12*(2*x-1)+6*12*(3*x+6)-1*6*8*(1-4*x) = 0
408*x+192*x-48+336 = 0
600*x+288 = 0
(600*x+288)/(6*8*12) = 0
(600*x+288)/(6*8*12) = 0 // * 6*8*12
600*x+288 = 0
600*x+288 = 0 // - 288
600*x = -288 // : 600
x = -288/600
x = -12/25
x = -12/25
