    Simplifying-1 (2x + 4) = 18

    Reorder the terms:-1 (4 + 2x) = 18 (4 * - 1 + 2x * - 1) = 18 (-4 + - 2x) = 18

    Solving-4 + - 2x = 18

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '4' to each side of the equation.-4 + 4 + - 2x = 18 + 4

    Combine like terms: - 4 + 4 = 00 + - 2x = 18 + 4-2x = 18 + 4

    Combine like terms: 18 + 4 = 22-2x = 22

    Divide each side by '-2'. x = - 11

    Simplifyingx = - 11
