Question

Simplify a - {b - [c - (d - e) - f] - g}.

a + b + c - d + e - f + g
a - b + c - d + e - f + g
a + b + c + d + e - f + g
a - b + c - d + e + f - g

Answer 1

a - {b - [c - (d - e) - f] - g}
= a - {b - [c - d + e - f] - g}
= a - {b - c + d - e + f - g}
= a - b + c - d + e - f + g.
so ur answer is the third one C there all equivalent so the last one is the answer choice so there u go

Answer 2

`a - b + c - d + e - f + g`

Explanation:

We know that,

(-)(-) = (+),

(-)(+) = (-),

(+)(-) = (-)

(+)(+)=(+)

Now,

Here, the given expression is,

`a - \{b - [c - (d - e) - f] - g\}`

`a-\{b-[c-d+e-f]-g\}`

`a-\{b-c+d-e+f-g\}`

`a-b+c-d+e-f+g`

Hence, Second option is correct.
