If x/y + y/x = -1 , ( x unequal y, y unequal 0) then the value of x^2 - y^2 is?
Maurinko [17]

Take your original equation \frac{x}{y} +\frac{y}{x} =-1

and multiply both sides by xy to remove the fractions. You are left with

x^2+y^2=-xy

So, x^2+y^2=-xy

Update: There is no numerical answer that can be found without being given a value for either x or y

For water 1 gram = 1 ml.

This means 45 grams are equal to 45 ml's.

Neither one is greater than the other one as they are equal.

The problem doesn't state what is being measured, so the answer could be different depending on the density of the product being measured.
