6-6(3x - 1)= -42

  • math - ,

    First, expand the term in parentheses (do the multiplication by 6)

    6 -18x +6 = -42
    Then, more all the constants to the right (changing signs when you do).
    -18x = -42 -6 -6 = -54
    Multiply both sides by -1
    18x = 54
    Divide both sides by 18.
    x = 54/18 = 3
