Equation 2 tells you that y is x  3 so you can substitute x  3 for y in the first equation.
Simplification gives me
Solve this equation for x and then substitute the value of x into equation (2) to find y. Once you have values of x and y you can substitute them into equation (1) to verify your answer. I hope this helps,
