x and y can be related if there is a constant of variation between the two numbers. This can be solved by simply multiplying the value of y to the value of x.
Example:
x = 4
y = 5
Determine y, when x = 10
In order to determine the value of y, when x = 12, we first need to solve for the constant of variation of x and y.
k = xy
k = (4)(5)
k = 20
Substitute the value of k, and the second value of x then solve for y.
20 = 10y
Divide both sides by 10 to determine the value of y.
y = 2
