Simplify the expression.
(4x + 9y) - (11x - 3y +7)
To simplify the expression, we first remove the parentheses.
(4x + 9y) - (11x - 3y + 7)
= 4x + 9y - 11x + 3y - 7
= (4x - 11x) + (9y + 3y) - 7
= -7x + 12y - 7
To simplify the expression, we need to combine like terms.
First, distribute the negative sign inside the parentheses:
(4x + 9y) - 11x + 3y - 7
Now, let's collect the like terms:
(4x - 11x) + (9y + 3y) - 7
Combining like terms:
-7x + 12y - 7
Therefore, the simplified expression is -7x + 12y - 7.
