Answer:
x=9
Step-by-step explanation:
subtract 22 from both sides, simplify 3x = 10x-63, subtract 10x from both sides of the equation, simplify -7x = -63, divide both sides of the equation by the same factor -7x/-7 = -63/-7, then simplify
There are two points of intersection
(-4,1) and (1,-4)
Both add up to 180 degrees
