According to statistics, a person will devote 33 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?

Let n represent the number of years watching TV.

Then let sleeping represent as n+19.

Solution for this problem is:

n+n+19=33

2n=14

n = 14 divided by 2

n=7

7 years are spent watching TV while 26 years are spent in sleeping.

Other solution:

To figure out how many years you spend sleeping and watching TV, you first need to take the number in total, which is 33, and subtract the number that you will exceed sleeping.33 – 19 = 14. Now that you have the number 14, you can see that 14 divided in 2 = 7. 7 +19 = 26. This leaves you with a remainder of 7 hours watching TV and 26 hours sleeping. 26 is 19 greater than 7. 7 + 26 = 33.
