Answer

{$(1,2),(9,6)$}

Work Step by Step

Two equations, we have $y^2=4x$ and $x=2y-3$ From the second equation, we have $y^2=4(2y-3)$ or, $y^2-8y+12=0$ or, $(y-6)(y-2)=0$ Thus, $y=${$2,6$} From the second equation when $y=2$, we have $x-2(2)+3=0$ or, $x=1$ and From the second equation when $y=6$, we have $x-2(6)+3=0$ or, $x=9$ Hence, the solution set: {$(1,2),(9,6)$}
