x-4/4+3x+5/2=12

OpenStudy (anonymous):

(X-4)/(4+3X)+5/2=12 2(X-4)+5(4+3X)/2(4+3X)=12 2(X-4)+5(4+3X)=12*2(4+3X) SOLVE IT FURTHER BY YOURSELF. . .

hero (hero):

@theyatin, how do you know the fraction isn't: \(\large\frac{x-4}{4} + \frac{3x+5}{2} = 12\)

OpenStudy (anonymous):

thats how is is written in the lesson

hero (hero):

See why it is important to use parentheses?

OpenStudy (anonymous):

well i used my own perception if she would not be satisfied with my answer she wil post it again :P

OpenStudy (anonymous):

thank you my hero :*

hero (hero):

Yeah, and perception doesn't always work with these kinds of problems.

OpenStudy (anonymous):

i appreciate your help theyatin.

hero (hero):

@hannah2013, how did he help you? The problem wasn't set up correctly.

OpenStudy (anonymous):

anytime hennah antway now problem is even easier. . . just multiply both sides with 4

hero (hero):

Actually, just multiply the second fraction by 2/2

hero (hero):

Then add the fractions and cross multiply

hero (hero):

\(\frac{x-4}{4} +\frac{6x + 10}{4} = 12\)

hero (hero):

\(\frac{7x +6}{4} = 12\)

hero (hero):

7x + 6 = 48

OpenStudy (anonymous):

LOL do it as hero says . . . *off*

hero (hero):

7x = 42 x = 42/7 x = 6

OpenStudy (anonymous):

Thank you both.

hero (hero):

I would have been able to help @theyatin as well if he knew how to use latex

OpenStudy (anonymous):

aaal credit goes to "hero" very bad @hannah2013 dont thanz me at all. . .

OpenStudy (anonymous):

at least you both were nice enough to help.

hero (hero):

@theyatin , it's always good to know what the problem is before you start helping. That's what I was trying to do yesterday. I was trying to get you to post the problem correctly so that I could help you.

OpenStudy (anonymous):
