X percent of y is y percent of X See related link.
x exceeds y by one
If two variable, X and Y are in direct variation, then the proportion of X/Y or Y/X has a constant value.
That depends on how "x" and "y" are related. For example, if you happen to know that there is a linear relationship, you can use the rule of three to calculate the missing value. But if you don't know how "x" and "y" are related, it can be ANYTHING.

If the value (not mean value) of y is related negatively to the value of x then larger values of x are associated with smaller values of y.

x + 1 = y y + 3 = z z = y + 3 = (x + 1) + 3 = x + 4 Or: x = y - 1 = (z - 3) - 1 = z - 4 Which results in the same: x exceeds z by 4.
Suppose sqrt(16) = x and cuberoot(16) = y, then then x^2 = 16 = y^3 so that x^(2/3) = y x = y^(3/2).
If there are two variables X and Y such that changes in the value of X cause changes in the value of Y but changes in Y do not cause changes in X, then X is the independent variable and Y is the dependent variable.However, if changes in the value of X cause changes in the value of Y and changes in Y cause changes in X, then both X and Y are dependent variables.
Substitute X for Y and Y for X, then solve for the new Y. The result is y = 3/(x-10). The steps are a bit difficult to show here, but you can see them by clicking the link in the "related links" section.
When y equals 0, x can take on any value. This is because x and y are independent variables, meaning the value of x is not dependent on the value of y in this case. Therefore, x can be any real number when y equals 0.
The answer depends on how x and y are related. Since you have not bothered to share the nature of that relationship, I cannot provide a more useful answer
