First multiply 2 sides by x so that the 'x' on the left hand side can be cancelled |dw:1333348939115:dw|
Callisto
  • Callisto
Then you'll get 6 = 12x. Do you understand it so far?
anonymous
  • anonymous
oh ok
anonymous
  • anonymous
|dw:1333349065270:dw| right
Callisto
  • Callisto
Then divide both sides by 12 so as to get rid of '12' on the right hand side |dw:1333349075104:dw|
Callisto

anonymous
  • anonymous
oh ok
anonymous
  • anonymous
|dw:1333349146311:dw|
Callisto
  • Callisto
you cannot cancel it like that... You can only cancel the common factors on the same side ...
anonymous

|dw:1333349346588:dw|
Callisto

|dw:1333349330185:dw|
Callisto
  • Callisto
Do you understand this part?
anonymous
  • anonymous
yes
Callisto
  • Callisto
Hmmm Can you try the right hand side? |dw:1333349567253:dw|
anonymous
  • anonymous
you can'y
Callisto
  • Callisto
Nah, what do you mean?
anonymous
  • anonymous
|dw:1333349786096:dw|
Callisto
  • Callisto
Yup, so can you get the result now?
anonymous
  • anonymous
|dw:1333349963430:dw|
Callisto
  • Callisto
Hmm.. not really.. from the workings, you can get 1 x -- = --- 2 1 Can you simplify it from here?
anonymous
  • anonymous
|dw:1333350116389:dw|
Callisto
  • Callisto
Well.. it's not like that.. You need to know that for an equation, the 2 sides are equal.
Callisto
  • Callisto
To solve an equation, you need to put the unknown on one side... like x +2 = 3 You need to minus 2 from both sides x +2 -2 = 3-2 So you can get x = 3-2 That is x =1 Do you understand so far?
anonymous
  • anonymous
forgot
anonymous
  • anonymous
so in this case we get 1/2+x=1
Callisto
  • Callisto
In which case? your question?
anonymous
  • anonymous
ohhhhh
Callisto
  • Callisto
To be frank, do you know who to solve an equation?
anonymous
  • anonymous
YES I DO
anonymous
  • anonymous
but in this case what do I need to solve
anonymous
  • anonymous
that's where im confused
Callisto
  • Callisto
Solve for x
Callisto
  • Callisto
6 --- = 12 x As I've said, you should multiply both sides by x because x is in denominator of the fraction
anonymous
  • anonymous
kk i got that
Callisto
  • Callisto
just like y -- = 2 6 You'd multiply both sides by 6 to get rid of the 6 on the left hand side y 6 x -- = 2 x 6 6 So you'll get y = 2x6 = 12. Then you finish solving for y
anonymous
  • anonymous
so how do we form the equation?
Callisto
  • Callisto
that another thing, what do you mean exactly?
anonymous
  • anonymous
ok we where up to the part in canceling..? then I lost you
anonymous
  • anonymous
with making up an equation?
Callisto
  • Callisto
Alright, sorry, then just concentrate on your question. I made it up because i thought it would be simpler for you to understand..

Callisto
  • Callisto
no... |dw:1333351565455:dw|
anonymous
  • anonymous
what is the next step
Callisto
  • Callisto
|dw:1333351617231:dw|
anonymous
  • anonymous
then divide 6 by 12x
anonymous
  • anonymous
x=2
Callisto
  • Callisto
by 12 only...
Callisto
  • Callisto
|dw:1333351718109:dw|

  • anonymous
Look, 6/x = 12 To solve the equation, you take your given equation, which relates x to the numbers. Then you (1) ISOLATE THE VARIABLE -this means to get the variable on one side of the equation and all the numbers on the other side -you do this by doing the ORDER OF OPERATIONS in reverse. In your case, there are no +'s or -'s, so we move to * and / We need to remember that to do something to an equation, we have to do it to both sides for it to remain equal. So to isolate the variable, multiply BOTH sides by x Then we get 6 = 12x Now, we need to get the 12 on the other side. What can we do to both sides to get rid of the 12 on the right side to make it appear on the left. Once you do that, your variable will be isolated so all you have to do is simplify the resulting fraction, and that is your answer.

Callisto
  • Callisto
Yup. what's the next step???
anonymous
  • anonymous
kk
Callisto
  • Callisto
what do you get for the answer?
anonymous
  • anonymous
do we make an equation?
Callisto
  • Callisto
What do you mean?
Callisto
  • Callisto
Actually, when you see x= a constant, that is the answer to the unknown x. For your question, we don't make equation. We use equation to solve for x
anonymous
  • anonymous
|dw:1333352589713:dw|
Callisto
  • Callisto
it is not the answer.. the answer is in the form of x = (a constant) Can you try again?
anonymous
  • anonymous
|dw:1333352663345:dw|
Callisto
  • Callisto
no, how did you do it?
anonymous
  • anonymous
i don't know?
Callisto
  • Callisto
|dw:1333352759685:dw|
Callisto
  • Callisto
Hmm.. do u understand it now?
anonymous
  • anonymous
omg are you serious..
anonymous
  • anonymous
wow my work made me confused
Callisto
  • Callisto
Do I seem like not serious?
anonymous
  • anonymous
yes you do but I'm shocked
Callisto
  • Callisto
|dw:1333353420037:dw| Usually the unknown should be put on the left for the final answer. Why are you shocked?
anonymous
  • anonymous
the answer was right in front of me
Callisto
  • Callisto
lol, I was shocked too :P
Callisto
  • Callisto
So, do you understand it now?
anonymous
  • anonymous
yes
anonymous
  • anonymous
thanks
Callisto
  • Callisto
welcome . Glad to help :)
