    to solve this absolute value inequality, you'll need to solve these two separate ineqalities: \(\large 3x-2<7 \) AND \(\large 3x-2>-7 \) can you take it from here?

    its a similar process to solving an equation 3x - 2 < 7 add 2 to each side of equation: 3x < 9 divide by 3: x < 9

    yes the graph will be a line with an open circle at x= -5/3 and open circle at +3, shaded in between
