    substitute y from the second equation in the first equation. the first equation becomes a quadratic in x then you'll be easily able to solve it

    These are the answers after following @vamgadu's recommended procedure:\[\left\{\left\{x=-\frac{9}{4},y=-\frac{5}{12}\right\},\{x=2,y=1\}\right\} \]
