Question 67973
solve the inequality, with answer in interval notation

|2x-3| is less than or equal to 20
Because this is a less than situation it is an and situation and can be solved simultaneously like this.
{{{abs(2x-3)<=20}}}
{{{-20<=2x-3<=20}}}
{{{-20+3<=2x-3+3<=20+3}}}
{{{-17<=2x<=23}}}
{{{-17/2<=2x/2<=23/2}}}
{{{-17/2<=x<=23/2}}}
Interval notation:
[-17/2,23/2]
