Question

For how many pairs of positive integers (x, y) is x + 3y = 100?

Answer 1

Answer:

33 pairs

Step-by-step explanation:

If x+3y = 100, then there are many pairs of positive integers x and y to satisfy the relation. Some of them are. I think positive integers start at 1, don't they? So, there are 33 pairs, from y=1 to y =33.
