do you have an idea what to do or have you tried something already?
Well, I got |dw:1379882997265:dw| but it's incorrect
yeah, alright, let's fix this :)
Do you understand this? |dw:1379883062090:dw|
Yes, so we get 2c+2L=p/v
yes, next step
Get it? |dw:1379883307166:dw|
alright, next step
Multiply both sides by 1/2, in other words, divide both sides by 2 |dw:1379883445598:dw|
made a mistake, one sec
alright, what do you think is the result?
Okay, so we divied everything by 1/2
we multiply* everything by 1/2
opps srry mistake. yes multiply
don't confuse the two statements. we multiply everything by 1/2, same as we divide everything by 2 :)
so what next?
well now I am confused. wherre did the 1/2 come out of?
alright, here's what. \(\huge 1-1=0 \) do you agree?
alright, and do you know that, to move 1 to the other side of the equation, means to do this \(\huge 1-1+1=0+1 \) ?
alright, then you know that, whatever you do to the left side of an equation, you do the same to the right... yeah?
ah okay so that's y you put the 1/2 in.
exactly, we put the half in initially to cancel out out the 2 in 2L, but once we multiply the left side by 1/2, we have to multiply the right side by 1/2 as well
do you understand now?
okay so i got L= (1/2) p/v- (1/2)-2c
yup, can you simplify that?
i dont know how I would simplify the 1/2's
alright, i'll help you out
you'll have this, because the 2's will cancel out |dw:1379884930249:dw|
Thats what I got. Oh so I was rtight :)
you got the 2v up that's what was wrong lol :P the 2v must be down if you do it how i showed you
okay thanks :)
