(2/3)*((1/4)*x+5/3)-((1/4)*((2/5)*x-(1/3))) = 6 // - 6
(2/3)*((1/4)*x+5/3)-((1/4)*((2/5)*x-(1/3)))-6 = 0
(2/3)*((1/4)*x+5/3)+(-1/4)*((2/5)*x-1/3)-6 = 0
2/3*(1/4*x+5/3)-1/4*(2/5*x-1/3)-6 = 0
2/3*(1/4*x+5/3)-1/4*(2/5*x-1/3)-6 = 0
1/15*x-6+43/36 = 0
1/15*x-173/36 = 0
1/15*x-173/36 = 0
1/15*x-173/36 = 0 // + 173/36
1/15*x = 173/36 // : 1/15
x = 173/36/1/15
x = 865/12
x = 865/12
