1. I can solve the first bit, (1,3) and (6, 1/2) but the hence is mandatory so how can I start?

Truly grateful to one and all for even a hint...

First hint : so you have as one of the equations

Look at the original set of equations and think about why this hint is useful. Then try to do something similar with the other equation.

Compare the two, might help if you write the two a,b eqs. as and

Then compare against and

Clearly, you have the same situation if you let and
