Answer 2

Option 1)

`n+15-15<22-15`

Option 3)

`n+15-22 <22-22`

Option 4)

`n+15+6 <22+6`

Explanation:

We are given an inequality in the question:

`n+15 <22`

We have to find the inequalities equivalent to the given inequality.

1)

`n+15-15<22-15\\n + 15 < 22-15 + 15\\n +15 < 22`

which is equivalent to the given inequality.

2)

`n+15<22-15\\n +15 < 7`

which is not equivalent to the given inequality.

3)

`n+15-22 <22-22\\n+15 < 22-22+22\\n +15 < 22`

which is equivalent to the given inequality.

4)

`n+15+6 <22+6\\n +15 < 22+6-6\\n+15 < 22`

which is equivalent to the given inequality.

5)

`n+15-22 <22\\n+15< 22+22\\n+15<44`

which is not equivalent to the given inequality.
