You can put this solution on YOUR website!
Just go by the definition:
\n" ); document.write( "|x| = x, x>=o
\n" ); document.write( "|x| = -x, x\n" ); document.write( "\n" ); document.write( "Solution:
\n" ); document.write( "|x-7|>=2\r
\n" ); document.write( "\n" ); document.write( "a) if x>=o
\n" ); document.write( " then,
\n" ); document.write( " x-7>=2
\n" ); document.write( " x>=9\r
\n" ); document.write( "\n" ); document.write( "b) if x\n" ); document.write( " then,
\n" ); document.write( " x-7<=-2
\n" ); document.write( " x<=5\r
\n" ); document.write( "\n" ); document.write( "]-∞,5]U[9,+∞[ VALUES OF X. \n" ); document.write( "

\n" );
