Answer 2

The answer of the given expression is 24.

Explanation:

The given expression is :

`b-2a- c`

We have to evaluate it.

We have been given the values as:

a = –7, b = 3, and c = –7.

Now, substituting these values in the expression we get:

`3-2(-7)-(-7)`

`3+14+7`

= 24

Therefore, the answer of the given expression is 24.
