Anna has a total of 40 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 5 more than

twice the number of black goldfish. Which system of equations below can be used to describe the number of black and orange

goldfish in Anna's aquarium?

40=3y+5

Step-by-step explanation:

If orange is represented by x and black is represented by y

orange fish are 5 more than twice black

meaning, x=2y+5

Also, orignal equation would be 40=x+y

so it would be 40=(2y+5)+y

or, 40=3y+5

then solve

35=3y

so about 12 orange fish
