x in (-oo:+oo)
3*(x-y)-(x/2) = 5*y-(2*(2*y-(3*x)))-6 // - 5*y-(2*(2*y-(3*x)))-6
3*(x-y)+2*(2*y-(3*x))-(x/2)-(5*y)+6 = 0
3*(x-y)+2*(2*y-3*x)-(x/2)-5*y+6 = 0
3*(x-y)+2*(2*y-3*x)-x/2-5*y+6 = 0
(2*3*(x-y))/2+(2^2*(2*y-3*x))/2-x/2+(-5*2*y)/2+(2*6)/2 = 0
2*3*(x-y)+2^2*(2*y-3*x)-x-5*2*y+2*6 = 0
2*y-6*x-x-10*y+12 = 0
2*y-7*x-10*y+12 = 0
12-7*x-8*y = 0
(12-7*x-8*y)/2 = 0
(12-7*x-8*y)/2 = 0 // * 2
12-7*x-8*y = 0
12-7*x-8*y = 0 // - 12-8*y
-7*x = -(12-8*y) // : -7
x = (-(12-8*y))/(-7)
x = (12-8*y)/7
x = (12-8*y)/7
