Let x be the length of time spent sleeping and y be the length of time spent watching television.
You spend 37 years sleeping and watching TV, which means:
x+y=37(1) 
The amount of years spent sleeping will be 19 more than those spent watching TV, so:

x=y+19(2) 
Solve by substitution. Substitute (2) to (1) and solve for y: 
(y+19)+y=37 
2y+19=37 
2y=18 
y=9 
Solve for xx using (2): 
x=9+19 
x=28 
You thus sleep for 28 years and watch TV for 9 years.
