I don't know :(

SOLVING AN ABSOLUTE INEQUALITY
lET X BE A VARIABLE OR AN ALGEBRATIC EXPRESSION AND LET A BE A REAL NUMBER SUCH A>0.
1. tHE SOLUTION OF [x]<a are all valuesof x that lie between -a and a. That's is.if [x] < a if and only if -a < x <a.
2 The soluion of [x] > a are all values of x that are less than -a or greater than a. That is [x] > a if and only x<-a or x>a.These rules are also valid if < is replaced by <and > is rep-laced by
>.
