x in (-oo:+oo)
2*((3/4)*x-1)+(1/2)*x = (1/4)*x+6 // - (1/4)*x+6
2*((3/4)*x-1)+(1/2)*x-((1/4)*x)-6 = 0
2*((3/4)*x-1)+(1/2)*x+(-1/4)*x-6 = 0
2*(3/4*x-1)+x/2-x/4-6 = 0
(4*2^2*(3/4*x-1))/(2*4)+(4*x)/(2*4)+(2*(-x))/(2*4)+(-6*2*4)/(2*4) = 0
4*2^2*(3/4*x-1)+4*x+2*(-x)-6*2*4 = 0
16*x-2*x-48-16 = 0
14*x-48-16 = 0
14*x-64 = 0
(14*x-64)/(2*4) = 0
(14*x-64)/(2*4) = 0 // * 2*4
14*x-64 = 0
14*x-64 = 0 // + 64
14*x = 64 // : 14
x = 64/14
x = 32/7
