Answer:
The correct answer here is A. x = 17.
How I found this out:
3x + 3 and 5x - 7 are going to be different solutions in the end.
I did the process of elimination.
First, I subsituted, 17 for x. 3 X 17 + 3 = 54. 5 X 17 - 7 = 78.
I then took 180 - 54 - 48 = 78 and 180 - 78 - 48 = 54, just to make sure they are positive numbers and not negative.
Since they work out, I chose this as my correct answer to your question.

I tried my best so I'm it's wrong.
Answer: 91
Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.
(74 + 92 + 83 + 100 + x)/5 = 88
(349 + x)/5 = 88
((349 +x)/5) x 5 = 88 x 5
349 + x = 440
x = 440-349
x = 91
Any number times 0 equals 0
