i'm math stage 2. going ok ish. any ways this is how to do similtaneous ( now idea in spelling, doing shit in english) equations (i think)
e.g.
a+b= 3
then it can be said that:
> a=b-3 (simple transformation)
then sub this for a:
=> (b-3)+b=3
you can also to this for 'b'
hope it helps. i've just finfished the unit on calcules. it's a shitter
