Systems of Linear Equations: Two Variables · Exercise 1

Determine whether the ordered pairs are solutions to the given system.

\left\{\begin{matrix} 3 x + y = 0 \\ x + 2 y = - 5 \end{matrix}\right at $\left(0,0\right)$ and $\left(1,-3\right)$

At (0, 0):

\begin{array}{|c|c|}\hline 3 x + y = 0 & x + 2 y = –5 \\ \hline \text{________________________ ________________________} & \text{________________________ ________________________} \\ \hline \text{________________________ ________________________} & \text{________________________ ________________________} \\ \hline \text{Conclusion: ________________________} \\ \hline\end{array}
