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
