Suppose `xy-5x+2y=30,` where x and y are positive integers. Find the number of possible values of x.

Suppose xy-5x+2y=30, where x and y are positive integers.Find the number of possible value of x .

If 12y=x^(3) and x and y are positive integers, what is the least possible value for y?

x^3 + x^2 + 16 is exactly divisible by x, where x is a positive integer. The number of all such possible values of x is

If x and y are positive integers and 3xy = 4 Then find the minimum value of 3x + 4y.

If x^yxxy^x=800 , then find x-y (where x and y are positive integers and xgt y ).

The number of solutions of the equation 2x + y = 40 where both x and y are positive integers and x le y .
