solve by the substitution method.
8x+3y=40
x=487y
THE ANSWER SHOULD BE AN ORDERED PAIR. PLEASE HELP ASAP

First you need to replace the x in the original equation with the given variable 487y
8(487y) + 3y = 40
384 56y +3y=40
56y + 3y = 40  384
53y = 424
53y/53=424/53
y=8 x=8
Ordered pair (8,8) 
sorry, I typed ordered pair wrong, the ordered pair is (8, 8)
