Answer 2

Let's simplify the expression step by step:

(5a - 3b) - (4 + 5a - 3b)

First, distribute the negative sign inside the second set of parentheses:

5a - 3b - 4 - 5a + 3b

Now, notice that the terms "5a" and "-5a" cancel each other out:

(-3b + 3b) - 4

The terms "-3b" and "3b" also cancel each other out, leaving:

0 - 4

Finally, subtract 4 from 0:

0 - 4 = -4

So, the simplified expression is indeed equal to -4:

(5a - 3b) - (4 + 5a - 3b) = -4
