For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

So, we have:

We add similar terms taking into account that:
Different signs are subtracted and the sign of the major is placed:

Answer:

Answer:
(A) x=-28
Step-by-step explanation:

Step-by-step explanation:
Step-by-step explanation:
If I'm understanding what a "proof" means, some answers could be:
2 + 3 = 5
4 + 15 = 19
8 + 21 = 29
Hope this helps you! Have a good night!
