Step 1

If x at least 5 multiples of 5 (but no more than 1 incorrect)

Answer

For x to be at least 5 multiples of 5, we can take values like: 5, 10, 15, 20, and 25. This results in x being: 5, 10, 15, 20, 25.

Step 2

If y is at least 5 multiples of 7 (but no more than 1 incorrect)

Answer

For y to be at least 5 multiples of 7, appropriate values could be: 7, 14, 21, 28, and 35. Therefore, the values for y are: 7, 14, 21, 28, 35.

Step 3

If y is a multiple of 5 and m is a multiple of 14

Answer

Choosing y = 35 (which is a multiple of 5) and m = 14 (which is a multiple of 14) fits the criteria that y and m are multiples of their respective values.

Step 4

If x = 35 and y = 14

Answer

For a correct set of values, we can select: x = 35, y = 14, which satisfies both x and y's conditions: x as a multiple of 5 and y as a multiple of 7.
