Ответ:
32 years
Step-by-step explanation:
Let the age of Carlos be represented by x
Then the age of Raul can be represented as the sum of twice the age of Carlos and 5.
In other words, Raul's age = 2x + 5
Sum of Carlos and Raul's age is 101
That is, \[x + 2x + 5 = 101\]
Or, \[3x + 5 = 101\]
Or, \[3x = 96\]
Or, \[x = 32\]
Hence, the age of Carlos is 32 years.
Age of Raul on the other hand is 2*32 + 5 = 69 years
Sum of their ages is 32 + 69 = 101 years.
