x in (-oo:+oo)
(2/5)*(x-2) = (1/4)*x+4 // - (1/4)*x+4
(2/5)*(x-2)-((1/4)*x)-4 = 0
(2/5)*(x-2)+(-1/4)*x-4 = 0
2/5*(x-2)-x/4-4 = 0
(2/5*4*(x-2))/4-x/4+(-4*4)/4 = 0
2/5*4*(x-2)-x-4*4 = 0
3/5*x-16-16/5 = 0
3/5*x-96/5 = 0
(3/5*x-96/5)/4 = 0
(3/5*x-96/5)/4 = 0 // * 4
3/5*x-96/5 = 0
3/5*x-96/5 = 0 // + 96/5
3/5*x = 96/5 // : 3/5
x = 96/5/3/5
x = 32
