    what do you get when you add 3x to both sides?

    When I mean SHOW I'm referring to a step by step interpretation of how to solve the problem. not directions.

    add (3x) to both sides would be more helpful :) but ill assume thats a typo..

    -3x+3x +4 = x+3x +8 0+4 = 4x+8 4 = 4x+8 now what?

    divide by for is possible; but there is an easier step first... we can -8 from each side to get that 4x by itself

    4-8 = 4x +8-8 -4 = 4x + 0 -4 = 4x ; now we can easily /4 -4/4 = 4x/4 -1 = 1x -1=x

    since we dint mess with multiplying or dividing the 'x' by a negative number; we can use the same sign -1 </ x

    draw a vertical line thru x =-1 and since -1 </ 0 is true; the origin is included in the area to be shaded
