Answer 2

Answer:

6

Step-by-step explanation:

In the equation, $\frac{23}{4} + -\frac{23}{4} --\frac{15}{4} + \frac{9}{4}$, we can see that $\frac{23}{4} + -\frac{23}{4}$ cancel each other out

This leaves us with $--\frac{15}{4} + \frac{9}{4}$. The negatives "negate" themselves giving us $\frac{15}{4} + \frac{9}{4} = \frac{24}{4}$ or $6$

Hopefully (some part of) this explanation makes sense (or at least somewhat). If this doesn't make sense, please tell me and I will try to make it more understandable as soon as possible.

It would help if you marked my answer as Brainliest, if I'm correct, so I can help even more people! (I would really appreciate it!)
