Answer 2

Answer:

The answer of the given expression is 24.

Step-by-step 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.
