X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3

Answer:
$47.92
Step-by-step explanation:
20% discount: $599 * 80% = $479.2 before tax
15% tax added: $479.2 + $71.88 = $551.08
Saved money: $599-$551.08= $47.92
