idk..

Subtract the bottom equation from the first equation so you have an equation in one variable. Solve for Y and substitute back into one of the original equations to get x.

it's basically like where you subtract the terms that share the same variable. for example, $2y - 2y$. so you would need to do the same with $y$ and $3y$, including $4$ and $0$.

2x + Y = 4
-2x -3Y = 0

-2Y = 4 Solve for Y. Then substitute into 2x + Y = 4 to get x.
