n in (-oo:+oo)
(-1/3)*(8*n+1) = (13/3)*n-7/3 // - (13/3)*n-7/3
(-1/3)*(8*n+1)-((13/3)*n)-(-7/3) = 0
(-1/3)*(8*n+1)+(-13/3)*n+7/3 = 0
(-13*n)/3-1/3*(8*n+1)+7/3 = 0
(-1/3*3*(8*n+1))/3+(-13*n)/3+7/3 = 0
7-1/3*3*(8*n+1)-13*n = 0
7-21*n-1 = 0
6-21*n = 0
(6-21*n)/3 = 0
(6-21*n)/3 = 0 // * 3
6-21*n = 0
6-21*n = 0 // - 6
-21*n = -6 // : -21
n = -6/(-21)
n = 2/7
