The aquarium has 3 more yellow fish than green fish. 60 percent of the fish are yellow. how many green fish are in the aquarium? show your work.

For this case we propose a system of equations:

x: Be the variable that represents green fish

y: Be the variable that represents the yellow fish.

According to the data we have:

We match the equations:

So, there are 6 green fish

6

There are 6 green fish in the aquarium.

Step-by-step explanation:

Let be "g" the number of green fish in the aquarium and "y" the number of yellow fish in the aquarium.

You can set up a system of equations:

Solve for "g" from the first equation and substitute this into the second equation and solve for "y":

Finally, substitute into , then:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
