Want me to help?

OpenStudy (calculusxy):

Sure :)

OpenStudy (anonymous):

$n = 10n - 10 $7 = (10 * 7) - 10 $7 = (70) - 10 $7 = 60

OpenStudy (anonymous):

so B

OpenStudy (calculusxy):

So 7 takes the place of all n's?

OpenStudy (anonymous):

Yes, 7 is n

OpenStudy (anonymous):

It would only be logical, what other number could it be? :)

OpenStudy (calculusxy):

Um.. Here is this other question which is similar. But can you help me? I mean I got quite an approach to this.

OpenStudy (anonymous):

Sure :)

OpenStudy (calculusxy):

If $n=120, then n=

OpenStudy (calculusxy):

Is n=13?

OpenStudy (anonymous):

Well it's the same equation right? $n = 10n - 10

OpenStudy (calculusxy):

Yeah

OpenStudy (anonymous):

Ok so you think it's 13? let's check :) $13 = 10n - 10 $13 = (10 * 13) - 10 $13 = 130 - 10 $13 = 120 So yes, it is 120

OpenStudy (calculusxy):
