    first combine like terms which are the Xs: -3x-6=-42

    Now get the X term alone which means you add -6 to each side: -3x=-36

    Now get rid of the coefficient in front of the X, so divide the -3: x=12

    12 is the answer

    4x-7x = 6-42

    -3x = -36

    3x=36

    x = 12

    - 7x - 6 + 4x = - 42

    - 3x - 6 = - 42

    - 3x = - 36

    x = 12.
