How To Set Up This Geometry Equation?

First I want to say this is my first post and that I'm a homeschooled student. This is my first year of high school without a hands on teacher and I'm having trouble with not being able to get in contact with my teacher when I have questions about the homework (I guess it's technically just work now, since it's all done at home).

I took a screenshot of the question to show you exactly what I'm working on.

The part that throws me off is that all of the numbers have X next to them and any equation I set up just doesn't add up right.

I tried 19x + 17x + 27x = 180, it came out to some kind of run on decimal like 2.85 something something. What am I doing wrong?

I even tried 19x = 27x and that just didn't even make sense.

My online textbook only shows how to find X if there is a problem like (19x + 30). I can't figure out a formula to solve a problem without that extra number like plus 30 or minus 10 that doesn't have an X.

I hope this makes sense. I could really use some help. This whole thing has me stressed out :(
 
Bless you pka!!

So it would be

1) 19x = 180 - 17x
2) 36x = 180
3) X = 5

Wow, I can't believe how simple that was. Thank you so much!
