Answer:

x=6

Step-by-step explanation:

x+7=3x-5

add 5 to both sides

x+12=3x

subtract x from both sides

12=2x

divide by 2 on both sides

6=x

Any one that knows this please help thanks!

You just need to plug the values: you have to multiply $x$ and $y^2$ , and then divide the result by -3.

So, if $y=2$ , we have $y^2=4$

Which means that $xy^2 = 5\cdot 4 = 20$

And the final answer is $\frac{20}{-3}$
