x = y - (50/y), where x and y are both > 0 If the value of y is doubled in the equation above, the value of x will

Correct Answer: increase to more than double

Explanation:

The best approach is to pick a number that satisfies the rules that x and y are greater than 0. So for example you could choose 25 for y.


The value of x before doubling is then 25 - 50/25 = 23


The value after doubling y will be 50 - 50/50 = 49, which is more than double.
