What exactly do you need to know about them? It's a pretty hard topic to explain through writing to be honest but if you give me a direct question that you're stuck on I could give it a go :)

can someone give me some common simultaneous equations? 

Answered Sun 5th June, 2011 @ 18:13 by lucy

eh????

well if both equations are linear then you add or subtract (depending on the sign: signs same subtract, signs different add)

if you get something like y=something and then an equation with x and y sqaured then substitute the y in

do you understand?
