The sum of three numbers is 110. the third number is 3 times the first. the first number is 5 more than the second. what are the numbers?

Let the second number be x.

First number = x + 5

Second number = 3 (x + 5) = 3x + 15

Sum = 110

x + x + 5 + 3x + 15 = 110

5x + 20 = 110

5x = 110 - 20

5x = 90

x = 18

Hence, the numbers are; 18, 23, 69.
