U is 10. If you subtract 11 first to get the variable and it's coefficient on its own, you see that 3u=30. To get the u on its own, you divide both sides by three. This gives you u=10
So, first, subtract 2.50 from 6.50 to get 4. Then, do 4 divided by 0.25 to get 16. Then add your fist hour to the 16 and your answer is 17 hours.
