(3*x)/4-((1/3)*(3*x-6)) = (5/2)*(6-(x/2)) // - (5/2)*(6-(x/2))
(3*x)/4-((1/3)*(3*x-6))-((5/2)*(6-(x/2))) = 0
(-1/3)*(3*x-6)+(-5/2)*(6-(x/2))+(3*x)/4 = 0
(3*x)/4-1/3*(3*x-6)-5/2*(6-1/2*x) = 0
(-1/3*4*(3*x-6))/4+(-5/2*4*(6-1/2*x))/4+(3*x)/4 = 0
3*x-1/3*4*(3*x-6)-5/2*4*(6-1/2*x) = 0
x+3*x-52 = 0
4*x-52 = 0
(4*x-52)/4 = 0
(4*x-52)/4 = 0 // * 4
4*x-52 = 0
4*x-52 = 0 // + 52
4*x = 52 // : 4
