According to the American Bureau of Labor Statistics, you will devote 32 years to sleeping and eating. The number of years sleeping will exceed the number of years eating by 24. Over your lifetime, how many years will you spend on each of these activities?

Assumptions:
  • Let years eating be e
  • Let years sleeping be s
We're given:
  1. s = e + 24
  2. e + s = 32
To solve this system of equations, we substitute equation (1) into equation (2) for s:
e + e + 24 = 32

To solve this equation for e, we type it in our math engine and we get:
e = 4

Now, we take e = 4 and substitute it into equation (1) to solve for s:
s = 4 + 24
s = 28
