Brendan Green · Answer 1

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
