Distribute, separate and then solve.

so far I got,
8yx16x2y

- Luigi0210

How did you get that?

by doing 8 times y and 8 times 2

- anonymous

hey @dreamer05 its 8y-16=2y
so,6y=16
y=8/3

- anonymous

how did you get 8/3?

- Luigi0210

@quantun No giving away answers or doing others work for them

- anonymous

@dreamer05 since 6y=16
y=16/6.Divide by 2 both in numerator and denominator you will get 8/3

- anonymous

but there is no option for that, unless it can be reduced? right.

- anonymous

i think you should check your question once again..:P

- anonymous

?

- Luigi0210

@dreamer05 you're right

- anonymous

yeah, i mean unless its -1 but I know that isn't right.. I am a little bit confused..

- Luigi0210

Reduce the fraction 16/6 by 2
This is why you guide not give answers

- anonymous

8/3

- Luigi0210

Is that one of your answer choices?

- anonymous

No,.. unless its 3. but that wouldn't make since.. would it?

- anonymous

@Luigi0210 what''s wrong in guiding ?

- Luigi0210

@quantun Nothing, I just don't think it's right for people do others work for them.
And Yea qua was right, did you write that question right?

- anonymous

I thought so, hold on..
8^(y-2)=2y

- anonymous

my bad..

- Luigi0210

That's so much better xD

- anonymous

SORRRY.

- anonymous

is it 8^(y-2)=2^y??

- anonymous

u have posted it wrong again...

- anonymous

sorry

- Luigi0210

Go easy on her :3

- anonymous

can you solve now?

- Luigi0210

@dreamer05 Do you know how to start?

- anonymous

Not really. I tried.

- Luigi0210

Well simple, get like bases.

- anonymous

8 and 2?

- anonymous

see 8 can be written as 2^3

- Luigi0210

Change 8 so it has a base of 2

- anonymous

compare both sides

- anonymous

what does that mean?

- Luigi0210

Yup, so now you have:
\[2^{3(y-2)}=2^y\]
Since the bases are the same, you can get rid of them and just solve: 3(y-2)=y

- anonymous

so it be, 3y-6=3y

- anonymous

R.H.S. will be 2y

- Luigi0210

Where did that 3y come from on the right?

- anonymous

sorry y

- Luigi0210

^

- anonymous

or not, idk i thought you were so suppose to add the 3 to the y.
so its just 3y-6=y

- Luigi0210

Now just solve for y..

- anonymous

-3

- Luigi0210

Try again

- anonymous

so, just 3?

- anonymous

bring y to one side and 6 to other and sovle

- Luigi0210

Yup

- anonymous

2y=6

- Luigi0210

This took a bit longer than expect but hey, you got it.

- anonymous

oh I did.. its 3?

- Luigi0210

Yup

- anonymous

YAY. sorry i'm really really really bad at math...

- Luigi0210

No it's fine, I've dealt with you before missy ;P

- anonymous

I know lolol...

- Luigi0210

Just keep trying and you'll be good :)

- anonymous

try to solve as many problems as you can

- anonymous

Thank you, thank you.
