    5x - 9 = 2x + 23

    Step-by-step explanation:

    5 times a number is represented by 5x, with x representing the unknown number.

    5x decreased by 9 is (5x - 9) since 9 is being subtracted by 9.

    (5x - 9) is equal to twice the number (2x), increased by 23.

    So, the equation is (2x + 23).

    Therefore, 5x - 9 = 2x + 23
