Question

If 3x^2=4y=12 what is the value ofx^2y

Answer 1

It would be 64 because x equals 2. Y=3

Answer 2

`\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=(12)/(3)\\ x^2=4\\ x=√(4)\\ \boxed{x=2} \end{cases}\quad \begin{cases} 4y=12\\ y=(12)/(4)\\ \boxed{y=3} \end{cases} \\\\\\ x^2y\implies (2)^2(3)\implies 4\cdot 3\implies 12`
