but i have no idea how they got it so

someone

PLZ HELP!!!!

**Tracy**, Tuesday, February 26, 2008 at 9:36amThe second equation is telling you what x is..since it says " x=2y-8" this tells you that wherever you see an x you can replace it with that equation, so you would get:

(2y-8)+5y-10=0

so then you would just solve for y to get 18/7. So now you know what y is you can put that answer in either equation and solve for x. for example:

x=2(18/7)-8

so x=-20/7
