Answer 3

Let's simplify the expression step by step:

Given expression: (b - c - 4.8) - (-c - b - 4.8)

First, let's remove the double negatives by changing the sign inside the second parentheses:

(b - c - 4.8) + (c + b + 4.8)

Next, let's simplify the expression by combining like terms:

b - c - 4.8 + c + b + 4.8

Rearranging the terms:

(b + b) + (-c + c) + (-4.8 + 4.8)

Simplifying further:

2b + 0 + 0

Simplifying further:

2b

So, the simplified form of the expression (b - c - 4.8) - (-c - b - 4.8) is 2b.
