If 4 less than 3 times a certain number is 2 more than the number ,what is the number?
e.3 Do I solve it like this:
3n-4=n+2?? If so, how do I solve this problem?
You have the equation right.

The answer is 3 (choice E).
If 3n-4=n+2... you need to breakdown the equation. Add 4 to both sides. So that leaves you with 3n=n+6. Subtract 1n from both sides. So that leaves you with 2n=6. Divide both sides by 2... therefore n=3.
