Question

Subtract 7x- (9+5x).

Answer 1

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

Answer 2

2x - 9

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
