Question

a-[a-b+a-{a-(a-b-a)}] simplify

Answer 1

Answer:

2b

Step-by-step explanation:

» a - [ a - b + a - { a - ( a - b - a ) } ]

= a - [ a - b + a - { a - a + b + a } ]

= a - [ a - b + a - { b + a } ]

= a - [ a - b + a - b - a ]

= a - [ a - 2b ]

= a - a + 2b

= 2b

Answer 2

Answer:

=2b

Step-by-step explanation:

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

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

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

=a-[a-b+a-a-b]

=a-[a-2b]

=a-a+2b

=2b
