    The solution of the information given will be as follows:

    5√ (x+7) = 10

    dividing both sides by 5 we get:

    √ (x+7) = 2

    squaring both sides we get:

    (x+7) = 2²

    x+7=4

    solving for x we get

    x=4-7

    x=-3

    thus the answer is x=-3

    this is an extraneous solution.
