    Answer: Yes

    Step-by-step explanation: Here, we want to decide if 3 is a solution for the equation 2n - 6 = 5n - 15. We can do this by simply plugging in 3 for n. If the statement holds true when 3 is plugged in for n, then 3 is a solution.

    Plugging in 3 for n, we have 2 (3) - 6 = 5 (3) - 15.

    2 (3) is equal to 6 and if we subtract 6 we get 0.

    On the right side, 5 (3) is equal to 15 and if we subtract 15 we get 0.

    0 = 0 is a true statement so yes,

    3 is a solution for the equation 2n - 6 = 5n - 15
