Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)
x = -3

Step-by-step explanation:
The formula for finding the interior angle sum of any polygon is (n - 2) x 180 where n is the number of sides, so...
(22 - 2) x 180 = 20 x 180 = 3,600 so the interior angles of a 22 sided polygon sum to 3,600 degrees.
Hope this helps :)
