Solve negative three v plus six equals nine for v

OpenStudy (oaktree):

So it helps to write it in math language first. Can you do that?

OpenStudy (anonymous):

v =-1

OpenStudy (anonymous):

-3v+6=9

OpenStudy (oaktree):

@Gabriel.Dalbani, enough. It really doesn't help people when you give them the answer like that. Persist and I'll have to report abuse of the forums. Anyway, that's right. So do you know inverse operations?

OpenStudy (anonymous):

yes

OpenStudy (oaktree):

Great. So what would be your first step to solving this equation?

OpenStudy (anonymous):

am not sure

OpenStudy (oaktree):

So you want to start by isolating the variable, right? So we need to get rid of that 6 that's hanging around near him. What would we do to get rid of it?

OpenStudy (anonymous):

divide by 6 to both sides

OpenStudy (oaktree):

Not divide. What is the 6 doing in relationship to the x? It isn't being multiplied.

OpenStudy (oaktree):

We would have to subtract 6. Right?
