Is (1,8) a solution to this system of equations?
y=x+7
y=4x+4
MathBot Answer:
True, $\left( 1, \ 8\right)$ is a solution of $y = x + 7 \text{ and } y = 4 x + 4$.
$$\begin{gathered}y = x + 7\\8 \stackrel{?}{=} 1 + 7\\8 = 8\end{gathered}$$$$\begin{gathered}y = 4 x + 4\\8 \stackrel{?}{=} 4 \left(1\right) + 4\\8 = 8\end{gathered}$$
