Subtract. (5z−3)−(3z−8) enter your answer, in simplified form, in the box.

   (5z − 3) − (3z − 8)
= 5z − 3 − 3z + 8
= 2z + 5

(5z−3)−(3z−8)

In order to solve this problem, we must first distribute the -1 into the (3z - 8)

5z - 3 - 3z + 8 

Next, we can combine like terms. We can combine everything that has a "z" in it together and anything that doesn't have a "z" together.

5z - 3z = 2z and -3 + 8 = 5

So your simplified answer is 2z + 5 

Hope this helped! 

Ithink the answer should be b.
