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

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\[3y+5=1/x\]

Yep.... :)
Good going..
Now Subtract 5 from both the sides and tell me where you arrive..
OpenStudy (anonymous):
\[3y=\frac{ 1 }{ x }-5\]

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.

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

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