In the given expression \(3x - 10 + 2y + 5\):
- The variables are \(x\) and \(y\).
- The coefficients are \(3\) and \(2\) (these are the numbers in front of the variables).
- The constants are \(-10\) and \(5\) (these are the standalone numbers without variables).
So the responses to fill in are:
- Variables: \(x\), \(y\)
- Coefficients: \(3\), \(2\)
- Constants: \(-10\), \(5\)
