    Step-by-step explanation:

    I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".

    Let x be the number.

    Ratio is division.

    (x-7) / (x+7) = 2

    Multiply by (x+7) on each side:

    x-7=2 (x+7) = 2x+14

    Add 7 on each side

    x=2x+21

    Subtract 2

    -x=21

    x=-21
