HELPPP PLZZZZ this is literally my LAST question. Find x, show ur work

Answer:
The answer is obviously -42.
Step-by-step explanation:
You add all the values on the shape to get 3x+486=360. You then subtract 486 on both sides to get 3x=-126. From there, you divide by 3 to get -42.
Answer:
720=130+102+120+134+2x+x
720=232+254+3x
720=486+3x
720-486=3x
234=3x
234÷3=x
78=x
