+118723 how do I do equations
Hi Wolverine :)
Maybe you would like to be more specific. There are many different equations.
Basically, do must know order of operation, BODMAS (or whatever acronym you use)
Then with the equation you get rid of all the things you do not want in the OPPOSITE order to BODMAS (because you are 'undoing' an expression.
ex
3x+7=13
get rid of +7 (I call this a tack on) by subtracting it. BUT if you subtract it from one isde you must subtract it form the other side too
3x+7-7 = 13-7
3x = 6
Now there is an invisable times sign between the 3 and the x, I'll put that in
3*x=6
I need to get rid of the 3 and the opposite of multiply is divide so I divide by 3 - but I'll have to do it to the other side as well.
(3x)/3=6/3
x = 2
