3/4w+8=1/3w-7

OpenStudy (anonymous):

first isolate your variable then get your denominators to match through multiplying by 1 (for instance 1/3 times 4/4w, and 3/4w times 3/3 then combine the numbers

OpenStudy (anonymous):

dude isn't the answer -36?

OpenStudy (anonymous):

we can subtract 3/4w and 1/3w as one crosses from one side to another...so we will get 5/12w and -15 on another side...then you multiply both sides by 12 to get 5w=-180...then you simply divide by 5 to get w =-36....hope you saw what i did..

OpenStudy (anonymous):

yeah, that's what I was trying to say. I'm just not very good at explaining

OpenStudy (anonymous):

no prob dude i hope she understood....

OpenStudy (anonymous):

Its a bit easier to see this way :D\[\frac{3}{4}w+8=\frac{1}{3}w-7\]\[\frac{5}{12}w = -15 \because \frac{3}{4}-\frac{1}{3}=\frac{9-4}{12}=\frac{5}{12}and(+8)+(+7)=15\]so we take 1\3 and move it left then take 8 and move it right but we did it in 1 go \[5w=-180 \rightarrow w=\frac{-180}{5}\rightarrow w=-36\]

OpenStudy (anonymous):

Oh BTW \[\because\]is the sign for becasue :D

nyc

OpenStudy (anonymous):

When I moved the 8, I actually subtracted it from both sides, to give\[(-8)+(-7)=-15\]sorry

OpenStudy (anonymous):

lol it happens
