Given


\begin{gathered} -3y=x-5 \\ x+5y=7 \end{gathered}

Solution

I will solve your system by substitution.


\begin{gathered} −3y=x−5;x+5y=7 \\ Step:Solve−3y=x−5\text{ }for\text{ }x: \\ −3y+−x=x−5+−x\left(Add-x\text{ }to\text{ }both\text{ }sides\right) \\ −x−3y=−5 \\ \end{gathered}

The final answer


x=2\text{ }and\text{ }y=1
