what is the question??
OpenStudy (anonymous):
35a divided by 5c
OpenStudy (anonymous):
I can see that. What are you supposed to be doing with it?? Simplifying??
OpenStudy (anonymous):
when you divide, you only divide like terms.
so what in that question can be divided?
OpenStudy (anonymous):
well here is the full question. 5a(b-2c)=35c solve for b

35 and 7?
OpenStudy (anonymous):
if you are supposed to solve for b, distributing would complicate the problem.
First divide both sides by 5a. Do that first and post what you get
OpenStudy (anonymous):
b-2c=35c/5a ?
OpenStudy (anonymous):
nice now get b alone. What do you think you need to do?
OpenStudy (anonymous):
add 2c right? :D

yup. done and done
OpenStudy (anonymous):
but wait, would 35c/ 5a turn into 7c/a?
OpenStudy (anonymous):
or something? because you divide by 35 and 7?
OpenStudy (anonymous):
correct
OpenStudy (anonymous):
oh wait oh okay so the answer would be b=7 c/a -2c?

and be careful because you need a common denominator before you can add the 2c
OpenStudy (anonymous):
oh I ment +2c
OpenStudy (anonymous):
you should be able to just leave the answer as is
OpenStudy (anonymous):
so what would be the answer now? I am really confused!
OpenStudy (anonymous):
the one you posted a couple lines above, except +
