It seems like you've provided a linear equation \(2x + y = 4\) and a partial expression \(-2x + 25\). To provide you with useful assistance, could you clarify what you would like to do with these expressions?
For example, do you want to:
- Solve for \(y\) in terms of \(x\)?
- Solve the system of equations if there is another equation related to \(-2x + 25\)?
- Plot the equations on a graph?
- Combine or simplify the given expressions in some way?
Please provide additional details!
