    Since it's three consecutive integers, the equation will end up like this:

    x+x+1+x+2 = 396.

    Combine like terms. All the x's will add together to become 3x, while the ones without will be 1+2 = 3.

    3x+3 = 396.

    We need to start getting the x by itself. We must subtract 3 from both sides. This is how it should end up:

    3x = 393.

    Then, we will finally get x by itself by dividing 3 by both sides.

    x = 131. The answer is x = 131.
