      -2 - (4X) = 10
      -2 + 2 - (4X) = 10 + 2
       4X = 12
      4x/4 = 12/4
      X =  3

      -2  - (-4 * 3) = 10
      -2  - (-12) = 10
      -2 + 12 = 10
      10 = 10

        4x - (-2) = 10


        you cannot minus a negative so, the problem will become addition


        4x + 2 = 10


        then subtract 2 from both sides. Problem reads now


        4x = 8


        Divide both sides by 4


        x = 2

          Sorry read the problem wrong.

          -2 - 4x = 10
          +2 + 2
          -----------------
          4x = 12
          -- --
          4 4
          ----------------
          x = 3

            Let the number be y
            By question,
            -2- 4(times the number) = 10
            i.e. -2 - 4y = 10
            i.e. -2 - 10 = 4y
            i.e. -12 = 4y
            i.e -12/4 = y
            i.e. y = -3
            So, the required number is -3.

            Now solve the other related problems by yourself.
