Which system of equations models the following problem if x represents the number of angelfish Nancy bought and y represents the number of goldfish she bought?
Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish. How many of each type of fish did she buy?
{x+y=360y=8x
{x+8y=360y=8x
{x−y=360y=8x
{x+y=8y=360x
