Answer:
2x - 9
Step-by-step explanation:
7x - (9 + 5x) < distribute the - into the parentheses to get rid of them
7x - 9 - 5x < combine like terms
7x - 5x = 2x
-9 stays as it is as there are no other terms to combine it with
the answer is 2x - 9
7x-(9+5x)
pretend that there is 1 in front of the bracket.
7x-1(9+5x)
7x-9-5x
= 2x-9
Answer: 2x-9
