thanks again melody, you always have the answers

i still dont get how an x turned into a 1? i get it all up till there

y=2? i know im wrong but im still really confused, xy/-x=x-2/x im trying to find x. maybe its x-x=-y-2...so....0=y-2

how did you keep the x after you subtracted it from both sides?

whats it called when you multiplyed it by 12? is there a term for it?

thank you so much that really helped me out, i cant tell you how much clearer it is now

how do you calculate km2 and mi2? i know its Xkm times Xkm and mi times mi but i keep getting lost somewhere
