    Step-by-step explanation:

    2x - 2 = 10 + 20

    2x - 2 + 2 = 10 + 20 + 2

    2x = 32

    x = 32/2 = 16

    Plug this in, too.

    2 (16) - 2 = 10 + 20

    30 = 30 and they are equal!

    Answer: x = - 11/4 as a proper fraction; - 2.75 as a decimal.

    Step-by-step explanation:

    2x-2 = 10x + 20

    Combine like terms

    -2-20=10*-2*

    -22=-8*

    Divide both sides by 8

    x=-22/8

    =-11/4 or 2 3/4

    X = - 2.75

    Plug the value of x into the equation:

    2 (-2.75) - 2 = 10 (-2.75) + 20

    -5.5 - 2 = - 27.5 + 20

    -7.5 = - 7.5
