Combine like terms.
4, minus, 5, minus, 2, x, minus, 4, y, plus, 4, minus, 5, x, plus, 7, y
4−5−2x−4y+4−5x+7y

To combine like terms in the expression:

\[
4 - 5 - 2x - 4y + 4 - 5x + 7y
\]

1. Combine the constant terms: \(4 - 5 + 4 = 3\).
2. Combine the \(x\)-terms: \(-2x - 5x = -7x\).
3. Combine the \(y\)-terms: \(-4y + 7y = 3y\).

The simplified expression is:

\[
3 - 7x + 3y
\]
