Question

How do you solve `n + 5 < 11`?

Answer 1

`n < 6`

Explanation:

You treat inequalities the same as equations in this case as you are only adding and subtracting values which has no impact on the inequality sign:

What ever operation you perform on one side of the inequality you must balance it by performing the same operation on the other side of the inequality. In this case, substracting `5` to isolate `n`:

`n + 5 - 5 < 11 - 5`

`n + (5 -5) < 6`

`n + 0 < 6`

`n < 6`
