You can put this solution on YOUR website!
10-|2x-1|=4
\n" ); document.write( "isolate the absolute value
\n" ); document.write( "-|2x-1|=-6
\n" ); document.write( "Multiply by minus 1
\n" ); document.write( "|2x-1|=6
\n" ); document.write( "This is 2x-1=6; 2x=7; x=3.5
\n" ); document.write( "It is also 2x-1=-6; 2x=-5; x=-2.5
\n" ); document.write( ";
\n" ); document.write( "check
\n" ); document.write( "10-|7-1|=4 yes
\n" ); document.write( "10-|-5-1|=10-|-6|, but |-6|=6, so 10-6=4.
\n" ); document.write( "You can always get the first equation by removing the brackets. The second one requires sign changes. \n" ); document.write( "

\n" );
