Adrian’s age is one less than twice Carlo’s age. The sum of their ages is 50. What are their ages?
17,33
18,32
19,31
20,30
Explanation:
let x be Carlo’s age. Twice his age is 2x. One less than twice his age is 2x - 1 which is Adrian’s age. Since the sum of their ages is 50,
we have
x + (2x - 1) = 50.
Simplifying, we have 3x - 1 = 50. This gives us 3x = 51 and x = 17.
Therefore, Carlo is 17 years old and Adrian is 2(17) - 1 = 33 years old.
