Answer 2

Answer:

2b

Step-by-step explanation:

Given that,

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

now, consider

{a-(a-b-a)}        (Multiply'-' with inner value)

{a-a+b+a}={b+a}=>(1)

now,consider

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

from eq.(1)

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

[2a-b-a-b]=[a-2b]=>(2)

now, consider

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

from eq(2)

=>a-[a-2b]

=>a-a+2b

=>2b

∴a-[a-b+a-{a-(a-b-a)}] = 2b
