Can someone please tell me the steps I would have to take in order to answer the question below?

Answer:
Step-by-step explanation:
Add all sides together and set equal to 360
x+1 + x+2 + x+3 + x+4 =360
Combine Like Terms
4x + 10 = 360
get rid of the ten on both sides
4x = 350
Divide both sides by 4
x = 87.5
