Answer 1

NEED HELP PRONTO!

Answer 2

First, choose a variable to represent the number.
Let's use x for the number.

Answer 3

If the number is x, then what is "the product of 9 and the number"?

Answer 4

9 x n = 3 x n - 12. I can make the equation, but I am having trouble solving it.

Answer 5

Ok. Your equation is good. You used n for the variable.

Answer 6

Ok, now let's solve it together.

Answer 7

9n = 3n - 12
We want all n's on the left side, so we subtract 3n from both sides.

Answer 8

9n - 3n = 3n - 3n - 12
That eliminates the 3n from the right side giving us:
6n = -12
Ok so far?

Answer 9

so you subtract 3n from 9n right?

Answer 10

sorry, internet crshed.

Answer 11

I just really need the answer so my dad will stop bugging me.

Answer 12

Yes.

Answer 13

Now that you have
6n = -12
you want n alone.
n is being multiplied by 6, so divide both sides by 6
6n/6 = -12/6
n = -2

Answer 14

omg thank you.
