I'm assuming this are the equations:
x^3 + y^3 = 4
1/x^3 + 1/y^3 = -1
How do I solve this math question?

I believe you've misread the last part. It just says the *reciprocals* sum to -1, not the reciprocals of the cubes.
There's a hint with the picture and the mention of *gold*.
Would you like further help or can you take it from here?
