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

Jul 24, 2018

$n \ge - 3$

#### Explanation:

$8 n \ge 7 n - 3$

Subtract $\textcolor{b l u e}{7 n}$ from both sides:
$8 n \quad \textcolor{b l u e}{- \quad 7 n} \ge 7 n - 3 \quad \textcolor{b l u e}{- \quad 7 n}$

$n \ge - 3$

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!
