n in (-oo:+oo)
(1/5)*(2*n+1) = (2/3)*(n-1) // - (2/3)*(n-1)
(1/5)*(2*n+1)-((2/3)*(n-1)) = 0
(1/5)*(2*n+1)+(-2/3)*(n-1) = 0
1/5*(2*n+1)-2/3*(n-1) = 0
1/5*(2*n+1)-2/3*(n-1) = 0
13/15-4/15*n = 0
13/15-4/15*n = 0
13/15-4/15*n = 0 // - 13/15
-4/15*n = -13/15 // : -4/15
n = -13/15/(-4/15)
n = 13/4
n = 13/4
