    Hope this helps! (:
    Step-by-step explanation:
    By putting the numbers in the given equation,
    2x + 3 + 3x = 7x + 9
    5x + 3 = 7x + 9
    (5x + 3) – 7x = (7x + 9) – 7x
    (5x – 7x) + 3 = 9
    -2x + 3 = 9
    (-2x + 3) – 3 = 9 – 3
    -2x = 6
    -x = 3
    x = -3
    Therefore, our equation is correct which has a negative result.
    In place of 6 if we use 8, value of x will be negative again.
