    Answer: The number you are thinking is 1

    Solution:

    Let the number you are thinking be = x

    Multiplying the number by 7 = 7x

    Adding the number 2 = 7x + 2

    Multiplying the number by 2 = 2x

    Adding the number 7 = 2x + 7

    Both these equation are equal to one another

    7x + 2 = 2x + 7

    Simplify the equation,

    7x - 2x = 7 - 2

    5x = 5

    x = 1
