Re: How to solve an inequality?

You can try fourier_elim. There is a pre-processor to fourier_elim that
allows it to  solve some nonlinear inequalities.

 (%i11) load(fourier_elim)$

 (%i12) fourier_elim([abs(x - abs(5-x)) < 1],[x]);
 (%o12) [2<x,x<3]

 (%i13) fourier_elim([x + y < 1, x - y > 9],[x,y]);
 (%o13) [y+9<x,x<1-y,y<-4]

 (%i14) fourier_elim([max(-x,x) < 7 * x + 1],[x]);
 (%o14) [-1/8<x]
