Answer:
The answer is 37.
Step-by-step explanation:
First of all we use Pemdas. Add the parantheses first. So its 7-18(-5/3) then you multiple the -18 to 5/3 Because after Parantheses its Exponents multiplication. So it becomes 30. Then you add 7 to get 37. I hope this is helpful.
Where is the diagram?
linear pair
the sum of linear pair angles is 180 degree.
so if we apply 16 in place of x in both equations and add them we get 180
