if x/y = y/x times 5 then what is x?

Question

can you please help me I'm in desperate need of help

Answer 1

Your problem does not have unique answer, the answer is a formula

 

If you meant x/y = 5*y/x  then by cross multiplying you get 5y² = x²

 

Taking square root on both sides you get x = +/- square root (5y^2)
