Question 768893
{{{abs(x)<12}}}

solutions: {{{x < 12}}} or {{{sqrt(x^2) < 12}}}

{{{ graph( 600, 600, -15, 15, -15, 15,abs(x), 12) }}} 

shade the triangle area between formed by {{{abs(x)}}} and line parallel to x-axis that goes through {{{y=12}}} excluding that line

so, solutions are all values of {{{x}}} in

interval: ({{{-12}}},{{{12}}})
