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.
