[QUOTE=jjjjj;482788]x-2<1and-x<2
First graph x- 2< 1 and -x< 2 separately. The solution to this problem is where the two graphs overlap (the intersection of the two sets).
Graph x+ 4< 5 and $\displaystyle -1\le x+ 2$ separately. The solution to this problem is the union of the two sets.x+4<5AND -1< OR = X+2
