Work Step by Step

We would want to use substitution to solve this system of equations because one of the equations already has $y$ expressed in terms of $x$. We can use the expression given for $y$ to substitute into the other equation to find the value for $x$ first. Once we have this value, we can substitute that value in for $x$ in one of the equations to solve for $y$.
