Question 388085: sean is five years older than peter. if the sum of their ages is at most 37 years, what is the olders that peter can be
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
x = sean's age.
x - 5 = peter's age.
x + x-5 <= 37
combine like terms to get:
2x - 5 <= 37
add 5 to both sides to get:
2x <= 42
divide both sides by 2 to get:
x <= 21
peter's age is x-5
the oldest peter can be is 21-5 = 16
when peter = 16, sean = 16 + 5 = 21
21 + 16 = 37
