n in (-oo:+oo)
(-2/5)*(n-(1/5)) = (-1/5)*(n+1/8) // - (-1/5)*(n+1/8)
(-2/5)*(n-(1/5))-((-1/5)*(n+1/8)) = 0
(-2/5)*(n-1/5)+(1/5)*(n+1/8) = 0
1/5*(n+1/8)-2/5*(n-1/5) = 0
1/5*(n+1/8)-2/5*(n-1/5) = 0
21/200-1/5*n = 0
21/200-1/5*n = 0
21/200-1/5*n = 0 // - 21/200
-1/5*n = -21/200 // : -1/5
n = -21/200/(-1/5)
n = 21/40
n = 21/40
