    Answer:

    Y = 963

    Step-by-step explanation:

    The digits of Y add to 18.  The first digit is 3 times the third digit.  The second  digit is 2 times the third digit.  Y is a three digit number.​

    Let Y a three digit number be: abc

    First digit = a , Second digit = b, Third digit = c

    Also given,

    The digits of Y add to 18. => a+b+c = 18     eq(i)

    The first digit is 3 times the third digit. => a = 3c     eq(ii)

    The second digit is 2 times the third digit. => b = 2c     eq(iii)

    Putting value of a and b in eq(i)

    3c + 2c + c = 18

    6c = 18

    c= 18/6

    c = 3

    Putting value of c in eq(ii) and eq(iii)

    a= 3c => a=3(3) => a= 9

    b= 2c => b=2(3) => b = 6

    Thus, Y = abc

    Y = 963
