The only solution is (4, -1/2).

The first one is wrong, because of you substitute X and Y or in this case (12, -5/2) into 3x+2y, you get 31=11, Which is an untrue mathmatical statement.

The second one is right, for the same reason. If you substitute X and Y you will get 11=11. which is a true statement.

The third one is wrong, because you have found a true statement.

The fourth one is wrong because you found an untrue statement.

Cortez's workout plan involves a total of 65 minutes of running and swimming. he burns 11 calories per minute when running and 9
Aleks [24]

The equation to model this would be 65 = 11r + 9s.

In this equation, we know that the total number he works is 65. We also know he burns 11 every time he runs for an hour. Therefore we can multiply 11 by r. We also know he burns 9 for every hour he spends swimming. Therefore we can multiply 9 by s.

When we put all three of these things together, we get 65 = 11r + 9s.
