I didn't try to calculate, but you have four equations of two unknowns, and 4C2 = 6, so you can try to pick all possible pairs to see whether you can find solutions that satisfy.

Sorry for the late reply

If you look at these 2 eqn

You can tell b2=ab

And a=b

Now if u put a=b all eqn are basically the same

Not related but r u using an ipad? If so what size is good for math

Never thought a bigger size would be better
