Quizplus · Accepted Answer

Solving the first equation for $x$ gives $x = \frac{-25 - 5y}{8}$. Substituting this expression for $x$ in the second equation and solving for $y$ yields $y = -5$. Substituting $y = -5$ back into the first equation to solve for $x$ gives $x = 0$. Therefore, the solution is $(0, -5)$.
