    Is x = -12 a Solution?

    Is x = -12 a solution to the linear equation
    2x + 6 = -18?

    My Work:

    Let x = -12

    2(-12) + 6 = -18

    The goal is to get the same value on both sides.

    -24 + 6 = -18

    -18 = -18

    Yes, x = -12 is a solution.

    Is my math correct?

    You ended up with -18 = -18:
    so why did you ask?
