Let X, Y and Z be points such that  XZ/XY = ZY/XY = 2.   If Y = (1,7), Z = (-1,7), then what is the sum of the coordinates of X?

There are 2 answers:

 

X(0.75, 6.031754163)           0.75 + 6.031754163 = 6.781754163 ≈ 6 25/32

or

X(0.75, 7.968245836)           0.75 + 7.968245836 = 8.718245836 ≈ 8 23/32
