If x = y/2 + 6, what is y in terms of x?

Question

anonymous · Answer

the problem looks like this, right?
$$x = \frac{ y }{ 2+6 }$$

anonymous · Answer

No! It's y over 2 plus 6!

anonymous · Answer

oh, ok. well in that case, you would subtract the 6 on both sides, then multiply by 2 to get your answer

anonymous · Answer

So i would get y by itself?

anonymous · Answer

yep

anonymous · Answer

so the answer would be 2x - 12 = y ?

anonymous · Answer

hm.. I got x - 12 = y..

anonymous · Answer

How? :( If you subtract 6 on both sides, you'd get x - 6 = y/2 , then you would multiply 2 to get y by itself, which would give me 2x - 12 = y

anonymous · Answer

when you multiply by 2, you can't multiply it by both the x and the 6.

anonymous · Answer

oh okay!

anonymous · Answer

does that make sense?

anonymous · Answer

eh a little

anonymous · Answer

you just have to remember to only multiply the number by a number because you can only combine like terms

anonymous · Answer

okay! thanks!

anonymous · Answer

anytime :)

anonymous · Answer

the problem isn't set up like that.

anonymous · Answer

$$x =  \frac{ y }{ 2 } + 6$$

anonymous · Answer

The problem is set up like that

anonymous · Answer

where did the 3 come from?

anonymous · Answer

it should look like this$$x= \frac{ y }{ 2 } + 6$$$$x - 6 = \frac{ y }{ 2 }$$$$x - 12 = y$$

anonymous · Answer

you're doing the wrong kind of problem. They asked what y was in terms of x.

anonymous · Answer

@SlightlyConfused just ignore this guy

anonymous · Answer

yeah i took the question in other way it would be like
$$x=\frac{ y }{ 2 } +6$$ $$x-6=\frac{ y }{ 2 }$$ $$2(x-6)=y$$ $$2x-12=y$$ $$y=2x-12$$ this is the correct answer

anonymous · Answer

now is it correct ??? @samanthablank

anonymous · Answer

@samanthablank I think @Ibad is correct on this one

anonymous · Answer

Simply because, 2x-12 is one of the multiple choices listed for this question

anonymous · Answer

ok.. maybe I was wrong.

anonymous · Answer

@samanthablank No it's fine!! Thanks for helping me

anonymous · Answer

Your too @Ibad

anonymous · Answer

*you

anonymous · Answer

ok, yeah I was wrong. This site ( http://www.mathway.com/default.aspx?subject=trigonometry)e says @Ibad is correct.

anonymous · Answer

no problem @samanthablank  , it happens, same i took question in a wrong manner 3 times,
in mathematics even a scientist can do a mistake :)

anonymous · Answer

haha yeah, true :)
