Question

How do you solve and graph `8n>=7n-3`?

Answer 1

`n >= -3`

Explanation:

`8n >= 7n - 3`

Subtract `color(blue)(7n)` from both sides:
`8n quadcolor(blue)(-quad7n) >= 7n - 3 quadcolor(blue)(-quad7n)`

`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 greater than it).

Hope this helps!
