You can put this solution on YOUR website!
The absolute value signs on the left side convert
\n" ); document.write( "whatever is inside the absolute value signs to a
\n" ); document.write( "positive number. The right side is also a positive
\n" ); document.write( "number, so the equation makes sense.
\n" ); document.write( "[ positive number ] = [ positive number ]
\n" ); document.write( "----------------------------------
\n" ); document.write( "Inside the absolute value signs can be $\"+7+\"$ or
\n" ); document.write( "it can be $\"+-7+\"$ and the equation is still true.
\n" ); document.write( " $\"+x+%2B+2+=+7+\"$
\n" ); document.write( " $\"+x+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+x+%2B+2+=+-7+\"$
\n" ); document.write( " $\"+x+=+-9+\"$
\n" ); document.write( "Those are the 2 solutions
\n" ); document.write( "check:
\n" ); document.write( "(1) $\"+abs%28+7+%29+=+7+\"$
\n" ); document.write( "(1) $\"+7+=+7+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+abs%28-7%29+=+7+\"$
\n" ); document.write( "(2) $\"+7+=+7+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
