If it were me, I'd solve the first equation for x.  That look simplest because the coefficient is already one (1).  Use that result to substitute into the second equation.  Use that result to solve for the final value of y.

Let's see it!

I didn't work the problem.  Please show you you did.

Did you solve the first equation for x?  Show me what you achieved.

Did you substitute this expression into the second equation?  Show me what you managed?

Did these step slead to the partial solution you suggested?  If so, then you should KNOW then answer and feel no need to ask if it correct.

Seriously, let's see your work!
