x in (-oo:+oo)
(1-(3*x))/2-((1-x)/4) = 3/8 // - 3/8
(1-(3*x))/2-((1-x)/4)-(3/8) = 0
(1-3*x)/2-((1-x)/4)-3/8 = 0
(1-3*x)/2+(-1*(1-x))/4-3/8 = 0
(4*8*(1-3*x))/(2*4*8)+(-1*2*8*(1-x))/(2*4*8)+(-3*2*4)/(2*4*8) = 0
4*8*(1-3*x)-1*2*8*(1-x)-3*2*4 = 0
16-80*x-24 = 0
-80*x-8 = 0
(-80*x-8)/(2*4*8) = 0
(-80*x-8)/(2*4*8) = 0 // * 2*4*8
-80*x-8 = 0
-80*x-8 = 0 // + 8
-80*x = 8 // : -80
x = 8/(-80)
x = -1/10
x = -1/10
