Use any of the values x = 1, 2, 3, . . . , 33 and the corresponding value of y = 100 - 33x.
Doing this way, you will get your answer 33 for the number of solutions.

Solving the given equation for y gives
y = 100-3x
Since 100 and 3x are both positive integers, y will also be a positive integer, as long as 3x is less than 100.
So as tutor @ikleyn says in her response, x can be any positive integer less than 100/3.
That gives us 33 solutions to the given equation with x and y both positive integers.
