Answer:
4x +4y -31
Explanation:
You want the simplified form of 9y - 3 (y + 1) - 2y + 4 (x - 7).
Simplified form
The expression is simplified by eliminating parentheses using the distributive property, then combining like terms.
9y - 3 (y + 1) - 2y + 4 (x - 7)
= 9y -3y -3 -2y +4x -28
= 4x +(9-3-2)y +(-3-28)
= 4x +4y -31
