Question

How do you solve `n+6<=3` and graph the solution on a number line?

Answer 1

`n <= -3`

Explanation:

`n + 6 <= 3`

Subtract `color(blue)6` from both sides:
`n + 6 quadcolor(blue)(-quad6) <= 3 quadcolor(blue)(-quad6)`

`n <= -3`

Here's a graph of it on a number line:

The closed circle on `-3` means that `-3` is one of the solutions (and anything less than it).

Hope this helps!
