Answer 1

Know what a quotient is?

Answer 2

the result of division?

Answer 3

Yes. So, if you have number / five = eight less than the number, how would you finish setting it up?

Answer 4

2?

Answer 5

No. Just take it one step at a time.

Lets use n for number.

So what is 8 less than n? Using +-/*, how can you write that?

Answer 6

8-n

Answer 7

That is n less than 8.

Answer 8

so n-8

Answer 9

Id I have 42 and I have 8 less than 42, then it is 42-8 = 36, so yes. n-8.

Now put it back together with the n/5 and you get:
\(\dfrac{n}{5}=n-8\)

Answer 10

Can you solve it now?

Answer 11

-2?

Answer 12

or 10?

Answer 13

\(\dfrac{n}{5}=n-8\)
\(5\left( \dfrac{n}{5}\right) =5(n-8)\)
n=5n-40
-4n=-40
n=10

Yah, I like that second answer a lot better!

Answer 14

okay thank you!
