Solve the given system of equation.

3x -Y =-7

To solve the system of equations:

1. Start with the given equation: 3x - Y = -7
2. Rearrange the equation to isolate one variable. Let's isolate Y:
Y = 3x + 7
3. Now we have the equation in terms of Y. The system is not fully defined with just one equation. Typically, there would be another equation in the system. If you have another equation, please provide it, so we can solve the system of equations.
