[tex]\bf 3x^2=4y=12\quad \begin{cases} 3x^2=4y\\ 4y=12\\ -----\\ 3x^2=12 \end{cases} \begin{cases} 3x^2=12\\ x^2=\frac{12}{3}\\ x^2=4\\ x=\sqrt{4}\\ \boxed{x=2} \end{cases}\quad \begin{cases} 4y=12\\ y=\frac{12}{4}\\ \boxed{y=3} \end{cases} \\\\\\ x^2y\implies (2)^2(3)\implies 4\cdot 3\implies 12[/tex]
