lynn is 6 years older than Linda.The sum of their ages is 36. What is Linda's age.

  • math -

    Let x = Linda's age

    x + x + 6 = 36
    2x = 30
    x = 15

  • math -

    This is pretty simple.

    Let Linda's age be x.

    So we have:

    x + (x+6) = 36
    2x + 6 = 36
    2x = 36 - 6
    2x = 30
    x = 30/2
    x = 15

    Double checking, if Linda is 15, Lynn will be 21.

    15 + 21 = 36

    So x is definitely 15.
