    The number is 18.

    7x18 = 126-25 = 101

    Start by representing the number. Let the number be x.

    Then "7 times a certain number" comes out to 7x.

    When 25 is subtracted from that, the result is 7x - 25 = 101.

    Add 25 to both sides: 7x = 126

    Finally, solve for x by dividing both sides of the equation by 7.

    x = 126/7 (reduce your answer).
