    -9

    Step-by-step explanation:

    n - a number

    five more: + 5

    twice a number: 2 · n = 2n

    five more than twice a number: 2n + 5

    The equation:

    2n + 5 = - 13 subtract 5 from both sides

    2n + 5 - 5 = - 13 - 5

    2n = - 18 divide both sides by 2

    2n/2 = - 18/2

    n = - 9
