Answer:
![\large\boxed{-17x-21}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/afz4sy5iqibb1l2ph3monts2lfauwqwm6i.png)
Explanation:
In this question, we're simply combining "like-terms" in order to simplify the expression.
Lets solve:
![-4+5x-17-22x\\\\\text{First, lets add 5x and -22x}\\\\-17x-4-17\\\\\text{Now we would add the -4 and -17. Adding 2 negatives still keeps it a negative}\\\\-17x-21](https://img.qammunity.org/2020/formulas/mathematics/middle-school/o60j84gzvhuthovdgt6r1e7mmrf1cnev2p.png)
When you're done solving, you should get -17x-21
This means that -17x-21 would be the simplified version.
I hope this helped you out.
Good luck on your academics.
Have a fantastic day!
