    Let a be the number

    And b be the other number.

    a is twice the other number means you add b two times or multiply it by two, 2b

    a is also 5 more than the above, that is you add 5 to 2b, a=5+2b …….(1)

    The sum of the two numbers means (a+b) and that is equal to 29, that is; a+b=29 ……(2)

    Substituting the value of a (or b will also work) in (2), we get:

    5+2b+b=29

    5+3b=29

    3b=29-5=24

    b=24/3=8

    Now that we have the value of b, and since a+b=29, then:

    a+8=29

    a=29-8

    a=21

    The answer: a=21, b=8

    To prove 21 is 5 more than twice 8, which is 16.
