    E. X=18 you can also just use Photomath or something if you need more help 🙂

    3(x – 4) = 3x – 12 (expand the brackets)
    3x – 12 = 2x + 6
    3x = 2x + 6 + 12 (put all of the integers on one side)
    3x = 2x + 18 (simplify – collect like terms)
    3x – 2x = 18 (put all of the unknowns on one side)
    x = 18 (simplify – collect like terms)

    Therefore, we know that x is equal to 18, and so the answer is E.
