I need to know how to actually solve this problem.

OpenStudy (anonymous):

OpenStudy (cggurumanjunath):

cross multiply .

OpenStudy (anonymous):

I am really bad at math. How do you cross multiply variables.

OpenStudy (anonymous):

Can you take it step-by-step please.

OpenStudy (cggurumanjunath):

35(x-1)=5(4x+2)

OpenStudy (anonymous):

35x-35? Is that the first part.

OpenStudy (cggurumanjunath):

yes

OpenStudy (anonymous):

I actually got it right. That is so exciting, I thought that I would get that wrong.

OpenStudy (anonymous):

I'm going to try the second part now.

OpenStudy (anonymous):

20x+10?

OpenStudy (cggurumanjunath):

yes

OpenStudy (anonymous):

Now what do I do?

OpenStudy (anonymous):

35x-35=20x+10, right?

OpenStudy (cggurumanjunath):

yes

OpenStudy (cggurumanjunath):

35x-20x=10+35

OpenStudy (anonymous):

15x=45

OpenStudy (anonymous):

I'm going to try and figure it out.

OpenStudy (anonymous):

15x/15=x 45/15=3, so that means x=3. Did I get that right?

OpenStudy (cggurumanjunath):

:)

OpenStudy (anonymous):

Wow, thanks you are so good at helping. Thank you so much. I finally understood that question.

OpenStudy (cggurumanjunath):

wc.
