Let ABCD be a trapezoid with bases AB and CD. Let AD = 5 and BC = 7, and let P be a point on side CD such that CP/PD = 7/5. If Q is a point on AB such that PQ is parallel to AB, then find AQ/QB.

So I have this math problem:

The solution of $8x+1 \equiv 5$ (mod $12$) is $x \equiv a$ (mod $m$) for some positive integers $m \geq 2$ and $a < m$. Find $a+m$.
