Best ResponseYou've already chosen the best response.0Lets take the second equation and make y the subject. \[y=517x\] Now place this value in the first equation. \[8x5(517x)=3\]Now solve this equation. \[8x255+35x=3\]\[43x=258\]\[x=258/43\]\[x=6\] Now place this equation in any of the above equations. Lets put it in the first equation.\[8(6)5y=3\]\[485y=3\]\[483=5y\]\[45=5y\]\[45/5=y\]\[y=9\]
