HELP PLZ!!!!!

Yves bought 420 tropical fish for a museum display. He bought 6 times as many parrotfish as angelfish. How many of each type of fish did he buy?

Which is a system of equations to model the problem if x represents the number of angelfish Yves bought, and y represents the number of parrotfish he bought?
(Points : 1)
x + y = 6
y = 420x

x + 6y = 420
y = 6x

x – y = 420
y = 6x

x + y = 420
y = 6x
