Answer
$x∈(-\infty;-3]∪[3;\infty)$
To graph the solution set, put two square brackets facing outwards at the points -3 and 3 ; the solution set is the space to the left of -3 and to the right of 3.
Work Step by Step
The absolute value of x is larger than 3, so the value of x is either larger than 3 or smaller than -3.
The soltuion set is any number whose distance to 0 is larger than 3.
