Let's simplify step-by-step.

9−x−(7+x)

Distribute the Negative Sign:

=9−x+−1(7+x)

=9+−x+(−1)(7)+−1x

=9+−x+−7+−x

Combine Like Terms:

=9+−x+−7+−x

=(−x+−x)+(9+−7)

=−2x+2

Answer:

=−2x+2
9 - {x - (7 + x)}
= 9 - { x - 7 - x }
= 9 - {-7}
= 9 + 7
= 16

In short, Your Answer would be 16

Hope this helps!
