Let t be the amount of time it takes to burn 205.8 calories, in minutes.

Our equation is 10.6*t+15=205.8.

This is because for every minute spent, 10.6 calories are burned, and 15 calories are burned no matter how long she swims. The other side is 205.8, because the total calories burned is equal to 205.8.
