Quizplus · Accepted Answer

Substitute $y = 3x + 13$ into the second equation: $x + 5(3x + 13) = -15$. Simplify to get $x = -5$, then substitute back to find $y = -2$.

Solve by Substitution y=3x+13x+5y=−15\begin{aligned}y & = 3 x + 13 \\x + 5 y & = - 15\end{aligned}yx+5y​=3x+13=−15​

Solve by Substitution $\begin{aligned}y & = 3 x + 13 \\x + 5 y & = - 15\end{aligned}$
