There are 31 fish in a tank. The fish are either orange or red. there are 17 more orange fish. How many fish are orange? How many fish are red? Define the variables, write and solve the system of linear equations.

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

41*67/2=1373.5
