Question

I am not so great at this it would be great if it would be explained than just an answer.
Question 1.1.
Choose the correct answer.

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

Answer 1

total fish= 420= x + y

parrot fish y = 6 times angel fish = 6 x

last set of eqns
