Answer 1

Add the first equation to the 3rd equation.

Then subtract the first equation from 2 times the 2nd equation.

This will give you a simple pair of simultaneous equations which you should be able to solve directly.

Answer 2

I provided instructions for obtainging two equations in two variables. Why were you unable to complete?
