-2/5 = x-((1/2)*(3*x-8)) // - x-((1/2)*(3*x-8))
(1/2)*(3*x-8)-x-2/5 = 0
1/2*(3*x-8)-x-2/5 = 0
(1/2*5*(3*x-8))/5+(5*(-x))/5-2/5 = 0
1/2*5*(3*x-8)+5*(-x)-2 = 0
5/2*x-20-2 = 0
5/2*x-22 = 0
(5/2*x-22)/5 = 0
(5/2*x-22)/5 = 0 // * 5
5/2*x-22 = 0
5/2*x-22 = 0 // + 22
5/2*x = 22 // : 5/2
x = 22/5/2
x = 44/5
x = 44/5
