-4

(the negative sign outside the absolute value signs is kept)

Answer 2

Answer: -4

Step-by-step explanation: We simplify inside the absolute value as our first step.

-7 + 3 is -4.

So we have -|-4|.

A common mistake at this point in the problem is to change the minus a negative to plus a positive but don't fall into this trap. We must ignore the negative outside the absolute value until our very last step in this problem.

So we take the absolute value of -4 which is 4 and we have -(4).

Remember to bring down the negative!

Notice that I used  around the 4 as it comes out of the absolute value.

So we have -(4) which is 4.
