• 1)

  12x + 8 = 42 + 9x - 4

  12x - 9x = 42 - 4 - 8

  3x = 30

  x = 30/3 = 10

  2)

  x = ½(180 - 120) = 30

  3)

  4x - 10 = 2(45)

  4x = 90 + 10

  4x = 100

  x = 100/4 = 25

• What do you mean "his wife's dead body"? WHOSE dead wife? We never find out what's in the box. That way you have to watch the sequel and hopefully find out then.
