    Answer:

    1. x = 8
    2. x = -6
    3. x = -7
    4. x = 10
    5. x = 4

    Step-by-step explanation:

    1. 2x+10-8x = -38

      -6x + 10 = -38

      -6x = – 48

       x = 8

    2. 2(x+5)=-2

       2x + 10 = -2

       2x = -12

        x= -6

    3. -10 = -5(x+9)

       -10 = -5x – 45

       35 = -5x

        x = -7

    4. 6 – 7x – 19 = -83

      -13 – 7x = -83

       -7x = -70

        x = 10

    5. 3(3x-4) = 24

       9x – 12 = 24

       9x = 36

       x = 4
