Solve this!

OpenStudy (howard-wolowitz):

\[\frac{ 3 }{ g }= \frac{ 4 }{ 3 } + \frac{ 1 }{ g+4 }\]

OpenStudy (howard-wolowitz):

@pitamar

OpenStudy (howard-wolowitz):

When i worked this I got -9/2 and 2

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \frac{3 }{g} =\frac{4 }{3}+\frac{1 }{g+4} }\) \(\large\color{black}{ \displaystyle \frac{3 }{g} =\frac{4\color{slateblue}{ \times (g+4)} }{3\color{slateblue}{ \times (g+4)}}+\frac{1\color{slateblue}{ \times 3} }{(g+4)\color{slateblue}{ \times 3}} }\)

OpenStudy (solomonzelman):

So, can you add the fractions together (after simplifying these multiplications).

OpenStudy (howard-wolowitz):

so |dw:1424889053107:dw|

OpenStudy (solomonzelman):

yes

OpenStudy (howard-wolowitz):

sorry im laggin a lot

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \frac{3}{g}=\frac{4g+16}{3g+12} +\frac{3}{3g+12} }\)

OpenStudy (solomonzelman):

I am also lagging... don't even know what is up with the site.... I guess many people are clicking and at least for some people the site has to not work (balance between bad and good). So, we, are the "bad ones" as far as that goes unfortunately.

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle \frac{3}{g}=\frac{4g+16}{3g+12} +\frac{3}{3g+12} }\) \(\large\color{black}{ \displaystyle \frac{3}{g}=\frac{4g+16+3}{3g+12} }\) \(\large\color{black}{ \displaystyle \frac{3}{g}=\frac{4g+19}{3g+12} }\)

OpenStudy (solomonzelman):

now, cross multiply

OpenStudy (howard-wolowitz):

yeah sometimes it will stop my screen from uploading and make me for buffer for a hour

OpenStudy (howard-wolowitz):

ok one sec

OpenStudy (solomonzelman):

it happens to me a lot. It is almost normal for me - that is horrible.

OpenStudy (howard-wolowitz):

ok so \[48g+57g\]

OpenStudy (solomonzelman):

when you cross multiply, you do this: \(\large\color{black}{ \displaystyle \frac{\color{blue}{3}}{\color{green}{g}}=\frac{\color{green}{4g+19}}{\color{blue}{3g+12}} }\) \(\large\color{black}{ \displaystyle \color{blue}{3} \times (\color{blue}{3g+12})~~=~~\color{green}{g} \times (\color{green}{4g+19}) }\) what do you then get ?

OpenStudy (howard-wolowitz):

9g+36

OpenStudy (solomonzelman):

yes, the left side. and the right side is ?

OpenStudy (howard-wolowitz):

4g+19g

OpenStudy (solomonzelman):

yes

OpenStudy (solomonzelman):

no

OpenStudy (solomonzelman):

it is g^2

OpenStudy (solomonzelman):

\(\large\color{black}{ \displaystyle 9g+36=4g^2+19g }\)

OpenStudy (solomonzelman):

like this, because (g) times (g) is (g^2) ... making sense?

OpenStudy (howard-wolowitz):

crap the stupid expoent
