    The sum of a number and its reciprocal is 72

    The phrase a number means an arbitrary variable, let's call it x
    x

    The reciprocal of the number is written as:
    1/x

    The sum of a number and its reciprocal means we add:
    x + 1/x

    The word is means an equation, so we set x + 1/x equal to 72
    x + 1/x = 72
