Answer:
i am not so sure but I think its 10x = 33
The mapping rule for 90 degrees counterclockwise would be (-y,x). So if you had (x,y) it would transfer to (-y,x). Yours is wrong it should be (4,-3). Remember
-(-4) is 4 and -3 stays as -3.
Basically, memorize these mapping rules.
Hope this helped!
So,

Multiply both sides by 11.

Divide both sides by 7.
f = 1
Check.


This checks.
S = {1}
This would be 1,711,596.
