Answer 1

first number is 15

second number is 21

third number is 63

15+21+63=99

Answer 2

First number: 21 | Second Number: 15 | Third Number: 63

Explanation:

First number = a

Third number = 3a

Second number = a - 6

a + a - 6 + 3a = 99

5a - 6 = 99

5a = 105

a = 21

Therefore, No.1 = 21, No.2 = 21 - 6 = 15, No.3 = 21 x 3 = 63

Hope this helps! :D
