Answer: There are 7 red fish, and 21 orange fish.
Step-by-step explanation:
x = amount of red fish
x + 17 = amount of orange fish
x + x + 17 = 31
2x + 17 = 31
2x +17 - 17 = 31-17
2x = 14
x=7
7+17 = 21
x = amount of red fish
x + 17 = amount of orange fish
x + x + 17 = 31
2x + 17 = 31
2x +17 - 17 = 31-17
2x = 14
x=7|| 7+17 = 21
