Thanks Badinage,

This is a very good question - one that is deserving of a proper answer.

I will try to give you some idea anyway

I will work through this example

3x+6 = -4+9

*  First you need to simplify each side independently. 

3x+6 cannot be simplified but -4+9=5    So the equation becomes

3x+6=5

Now you say - I want the lots of x by themself so what do I want to get rid of

ok I want to get rid of the +6   the opposite of +6 is minus 6  BUT

if I minus 6  from one side I have to minus 6  from the other side too.  The equation must stay balanced!

3x+6=5

     -6   -6

3x     = -1

NOW I want the x by itself so what do I need to get rid of.

 I need to get rid of the 3.  How do I do that?   Well between the 3 and the x is an invisable multiply sign

3*x=-1

The opposite of mult is divide and a divide is the same as a fraction line. So I have to divide both sides by 3

$$\\\frac{\not{3}*x}{\not{3}}=\frac{-1}{3}\\\\
x=\frac{-1}{3}$$

I hope that helps :)

I just put this thread in our reference material thread.  I don't want it to get lost.

Alan, can you make up another one so that I can try it on my own?  :/

Your answer is great Alan.  It's going straight to the Pool Room !!!

If you do not understand this GREAT compliment it is because you are not Australian.

It comes from an iconic Australian movie made in 1997 called "The Castle"

The movie is hilarious and also very sweet.  Here is an extract.

It is really the lowest common denominator that you need

BUT

that is the lowest common multiple of the denominators.  

Thanks  BrittanyJ,    

Did you give CPhill points - looks like you might have forgotten  

Yes radio made a little mistake.  

Thanks for pointing it out anon but it is no big deal :)

My 3 points to both of you :)

Mmm,  I do not know........

Really your question does not make much sense.
