Question

please answer fast.........

Answer 1

a - [ a - (b+a) - { a - ( a - ( b-a) ) } ]
= a - [ a - b - a - { a - ( a - b + a)}]
= a - { - b - ( a - 2a + b)}
= a - { - b - ( b-a)}
= a - ( - b - b + a)
= a - a + 2b
= 2b

If this helps u then only mark as brainliest.

Answer 2

it becomes like this   .........a-[a-b+a-{a-(a-b-a)}]
= a-[-b+{a-(-b)}]
=a+b+a+b
=2(a+b}
