    You could also write it as:

    1st child's age: = 2x

    2nd child: = 4x

    3rd child: = 5x

    2x+4x+5x=33

    11x=33

    x=3

    Then

    1st child's age: = 2x = 6

    2nd child: = 4x = 12

    3rd child: = 5x = 15

    To check if it's correct you need to sum up: 6+12+15=33

    2+4+5 is 11 and 33/11 is 3 so for every 1 is 3 years,

    the first is 2 so is 2x3=6

    the second is 4 so is 4x3=12

    the third is 5 so is 5x3=15
