x in (-oo:+oo)
3*(x+2)+x-(1/5) = x/2 // - x/2
3*(x+2)+x-(x/2)-(1/5) = 0
3*(x+2)+x-(x/2)-1/5 = 0
3*(x+2)+x-x/2-1/5 = 0
(2*3*5*(x+2))/(2*5)+(2*5*x)/(2*5)+(5*(-x))/(2*5)+(-1*2)/(2*5) = 0
2*3*5*(x+2)+2*5*x+5*(-x)-1*2 = 0
40*x-5*x-2+60 = 0
35*x-2+60 = 0
35*x+58 = 0
(35*x+58)/(2*5) = 0
(35*x+58)/(2*5) = 0 // * 2*5
35*x+58 = 0
35*x+58 = 0 // - 58
35*x = -58 // : 35
x = -58/35
x = -58/35
