Step-by-step explanation:

- ( 9 - ( m + a ))

= -( 9 - ( 4 + 3))

= - ( 9 - (7))

= -( 9 - 7)

= - 2

Answer:

-2

Step-by-step explanation:

Open the bracket first

-(9-(m+a))

-(9-m-a)

-9+m+a

So let's substitute the value for the m and a

-9+4+3

Using BODMAS

Addition comes before substration

So

-9+4+3

=-9+7

=-2

So the final answer is-2
