I hope this helps :)
The answer is 14/15 because we need to make the denominators the same before adding the numerators. It's all about finding the lowest common denominator which is 15. :)
Ok so u have to set them equal to 180 bc they r supp lines so 1.15+x=180 sub 15 from both sides x=165
2.28+x-4=180 combine like terms 28-4=24 rewrite 24+x=180 den sub 24 from both sides x=156
I will put the rest in the comments if you still don't know
