From
a%2F3-1%2F3=-3
We can calculate the least common multiple of the denominators, to cancel them out later. lcm(3, 1) = 3, so we convert the two sides to a fraction with denominator 3:
%28a-1%29%2F3+=+-9%2F3
We cut the denominators out:
a-1+=+-9
And solve.

Solve 1%2Aa%2B-1=-9. Move -1 to the right: 1%2Aa=-9--1. Divide by 1: a=%28-9--1%29%2F1=-8%2F1+=+-8


Therefore, a+=+-8
