To solve the system of equations, we can use substitution or elimination. Rearranging the second equation for x gives us $x = \frac{7.25 - 15.7y}{9.49}$. Substituting this expression for x in the first equation and solving for y, then substituting back to find x, gives us $x = -0.35$ and $y = 0.67$.
