-3z - (-z - 2)
In order to find the expression equivalent to our given expression, we have to simplify our given expression :)
-3z + z + 2
**Remember : the "z" and "2" become a positive because a negative times a negative is always a positive!**
Now, add like terms.
(-3z + z) + 2
Simplify.
-2z + 2
Look at our given answer choices.
Our answer is c. -2z + 2

Answer:
Linda makes 3 more cards than Paul.
Step-by-step explanation:
Let's express the affirmations into equations:
Paul (P) can make 1 card for every 3 cards Linda (L) makes:
(1)
Linda can make 3 cards for every 2 cards that Aaron (A) makes:
(2)
During a week, Aaron makes 72 cards, hence the number of cards of Linda and Paul can be calculated as follows:
From equation (2):

Now, from equation (1):

Finally, the number of cards that Linda makes more than Paul is:

Therefore, Linda makes 3 more cards than Paul.
