You can put this solution on YOUR website!
$\"+-2+%2B+abs%28+x+%29+%2B+9+=+10+\"$
\n" ); document.write( " $\"+abs%28+x+%29+%2B+7+=+10+\"$
\n" ); document.write( "Subtract $\"+7+\"$ from both sides
\n" ); document.write( "----------------------------
\n" ); document.write( " $\"+abs%28+x+%29+=+3+\"$
\n" ); document.write( "The absolute value is always positive
\n" ); document.write( "because
\n" ); document.write( " $\"+abs%28+x+%29+=+abs%28+-x+%29+\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"+x+=+3+\"$
\n" ); document.write( " $\"+x+=+-3+\"$
\n" ); document.write( "are both solutions
\n" ); document.write( "--------------------
\n" ); document.write( "I can demonstrate this by plotting
\n" ); document.write( " $\"+y+=+abs%28x%29+\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-6%2C+6%2C+-6%2C+6%2C+abs%28x%29+%29+\"$
\n" ); document.write( "Note that when $\"+x+=+3+\"$ , $\"+y+=+3+\"$
\n" ); document.write( "but also when $\"+x+=+-3+\"$ , $\"+y+=+3+\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
