Another problem I just crossed. Going to be last for tonight, I need to rest.

Okay, he is what I've done.

Divided off the r and got

I multiplied both sides of the equation by the reciprocal

Now here's where I'm lost.

I don't have the slightest clue what happened. Why did you change the problem? I know it's still the same, just been rearranged.

I tried solving it and still hadn't came out with the right answer.

I use distributive property 3(3r-3)=7r ; 9r - 9 = 7r ; 9r = 7r + 9 ; I don't get what's next - Dec 7th 2011, 05:33 AMskeeterRe: Solve the Equation
I made a typo in the previous equation ... the right side should be instead of

cross multiply ...

distribute on the left side ...

add 27 and subtract 7r from both sides ...

combine like terms on the left side ...

divide both sides by 20 ...

you're done. - Dec 7th 2011, 07:42 AMHellBunnyRe: Solve the Equation
I hate how I can look at a problem after its done and say to myself " I knew how to do that! " but couldn't figure out how to do it. Insane. Thanks you guys.
