Everett Wolf · Answer 1

The number of marbles is greater than or equal to 12.

The inequality would be:

8n-10≥6n+14

We need to gather all of the variables on one side, so we will subtract 6n from both sides:

8n-10-6n≥6n+14-6n

2n-10≥14

Now we will cancel the 10 by adding it:

2n-10+10≥14+10

2n≥24

Divide both sides by 2:

2n/2 ≥ 24/2

n≥12
