Ok. So, you want to find n. To do that, we can first combine like terms. 6n+2n. Just like regular addition, 8n. The outcome would be 8n=72. So, if we want to find n, we need to somehow eliminate the 8. Since 8 multiplied by n would give us 72, we need to divide eight from both sides to get our final answer. So 72/8=9. n=9
