x in (-oo:+oo)
(1/4)*(x+2)+2 = (1/8)*x+4 // - (1/8)*x+4
(1/4)*(x+2)-((1/8)*x)-4+2 = 0
(1/4)*(x+2)+(-1/8)*x-4+2 = 0
1/4*(x+2)-x/8-4+2 = 0
(1/4*8*(x+2))/8-x/8+(-4*8)/8+(2*8)/8 = 0
1/4*8*(x+2)-x-4*8+2*8 = 0
x-32+4+16 = 0
x-28+16 = 0
x-12 = 0
(x-12)/8 = 0
(x-12)/8 = 0 // * 8
x-12 = 0
x-12 = 0 // + 12
x = 12
x = 12
