i hope this helps :)
The sine model is y=10 sin(1/30 t) + 30. The 30 represents default distance from the ground, and the ten is required to represent the length of the blades. Every 30 seconds, one rotation completes, so t must be multiplied by 1/30.
14x+2y=6 (1)
-7x-2y= -13 (2)
Multiply (2) by 2, we have:
-14x-4y= -26 (3)
Take (1)+(3), we can solve and get x= -1, y= 10~
