Question

according to statistics, a person will devote 37 years to sleeping and watching TV. The number of years sleeping will exceed the number of years watching tv by 19. Over the lifetime, how many years will the person spend on each of these activities?

Answer 1

Ha!. It's not possible to sleep and watch TV at the same time!

 

Let x = number of hours sleeping, y = number of hours watching TV.

 

x+y=37, x-y=19;

 

x=28, y = 9
