simplify

1) (a-4)+(a-9)-(a-3)-(a+11) ​

Answer 1

The answer is " - 21 "

Step-by-step explanation:

( a - 4 ) + ( a - 9 ) - ( a - 3 ) - ( a + 11 )

=  ( a - 4 ) + ( a - 9 ) + ( - a + 3 ) + ( - a - 11 )

= 2a - 2a - 4 - 9 + 3 - 11

=  - 24 + 3

=  - 21 .

( a - 4 ) + ( a - 9 ) - ( a - 3 ) - ( a + 11 ) = - 21.

Answer 2

Answer:

Step-by-step explanation:

Lets first take out the brackets

a - 4 + a - 9 -a +3 -a -11

Now lets simplify

⇒-a + a -4 -9 -2a -11 +3

⇒-13 -2a -8

⇒-21 -2a

⇒-2a = 21

⇒a = 21/-2

⇒a = -21/2

Ans ⇒a = -10.5
