_

Answer 1

Focusing only on your final statement, "5y=5," I'd ask you to solve that for y. Once you have the value of y, substitute it into either of the given equations and find x.

This should give you the "solution," (x,y).

Try that point in the other equation. Is the resulting equation true?

Answer 2

Regardless, you still need to solve for x and y.
I am assuming that the instructions (missing) for this problem state: "Solve the following system of linear equations." That means: "Find (x,y) such that this point satisfies both of the given equations. Please try doing this. If not sure what to do, ask questions here.
