Question 352127
{{{x - 9 < 3x - 4 < x + 8}}} subtrac x from each group
{{{x-x - 9 < 3x-x - 4 < x-x + 8}}}
{{{- 9 < 2x - 4 < 8}}} add 4 to each group
{{{- 9+4 < 2x - 4+4 < 8+4}}}
{{{- 5 < 2x < 12}}} now divide each group by 2
{{{(- 5/2) < x < 6}}} 

draw an open circle at x=-2.5 and draw and arrow to the right
then draw an open circle at x=6 and draw an arrow to the left
where the two lines overlap is where the solution lines (between -2.5 and 6, not including those points)
