The first step in solving the system of equations is to **solve the first equation for y**.

Starting with the first equation:

\[ 3x + y = 23 \]

You can isolate \( y \) on one side of the equation:

\[ y = 23 - 3x \]

This will allow you to substitute the expression for \( y \) into the second equation if you choose to proceed that way.
