x=1/(3y+5)

OpenStudy (anonymous):

isolate y \[x=\frac{ 1 }{ 3y+5 }\]

OpenStudy (anonymous):

Multiply both the sides by (3y + 5) first... Can you do that??

OpenStudy (anonymous):

I am expecting a reply from your side @sgta101

OpenStudy (anonymous):

sry i was afk, so \[3xy+5x+1\]

OpenStudy (anonymous):

*\[3xy+5x=1\]

OpenStudy (anonymous):

There is no need of multiply x with it, just leave it in factor form: \[x(3y + 5) = 1\] Okay? Getting??

OpenStudy (anonymous):

kk

OpenStudy (anonymous):

Now divide by x both the sides..

OpenStudy (anonymous):

Go ahead...

OpenStudy (anonymous):

ahh i see, so\[3y+5=1/x\]

OpenStudy (anonymous):

Yep.... :) Good going.. Now Subtract 5 from both the sides and tell me where you arrive..

OpenStudy (anonymous):

\[3y=\frac{ 1 }{ x }-5\]

terenzreignz (terenzreignz):

What are you being asked to do?

OpenStudy (anonymous):

isolate y

terenzreignz (terenzreignz):

Well starting from here 3xy + 5x = 1 I want to bring everything without y to the right side.

OpenStudy (anonymous):

okay

terenzreignz (terenzreignz):

So, what do you get?

OpenStudy (anonymous):

\[y=\frac{ 1 }{ x3}-\frac{ 5 }{ 3 }\]

OpenStudy (anonymous):

?

terenzreignz (terenzreignz):

Yeah, that's correct, actually. Except, write it this way instead, the way you wrote it bothers me :) \[y=\frac{ 1 }{ 3x}-\frac{ 5 }{ 3 }\]

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

sry about that

terenzreignz (terenzreignz):

Good job, though.

OpenStudy (anonymous):

can i simplify it further?

terenzreignz (terenzreignz):

No. Unless you want only one fraction bar, in which case, it becomes \[y=\frac{ 1-5x }{ 3x}\]

OpenStudy (anonymous):

k that's what i meant

OpenStudy (anonymous):

thanks for the help

terenzreignz (terenzreignz):

No problem :)
