Question

What's the answer to 4n - 9 = -9

Answer 1

Hello!

You solve this algebraically

4n - 9 = -9

Add 9 to both sides

4n = 0

Divide both sides by 4

n = 0

The answer is 0

Hope this helps!

Answer 2

The answer you are looking for is "n = 0".

This can be found by adding 9 to each side, which would leave you with "4n = 0". To get "n" by itself, you'd then divide both sides by 4. "N" in this case would equal 0, because 0 divided by any number, will always be 0.

To check this answer, you could replace "n" with 0, and solve the left side. This would leave you with "-9 = -9", meaning the answer is correct.

I hope this helps!
