If mentioned that x and y are positive.
For positive integers
x=1 y=199 sum =200
x=2 y=198 sum =200
..
..
..

x=200 y=0 sum =200

Sum of all positive integers is = $$200 \times 200$$

If x and y are not mentioned to be positive then the sum is infinite. because we can rewirte the pairs

x= -Infinity y = 200 + Infinity sum=200
..
..
x=-2 y=202 sum =200
x=-1 y=201 sum =200
x=0 y=200 sum =200
x=1 y=199 sum =200
x=2 y=198 sum =200
..
..
..

x=200 y=0 sum =200

Sum of all integers is = $$Infinity \times 200$$
