You can put this solution on YOUR website!
We're told that p = -2. So wherever you see a 'p', you replace it with -2.
\n" ); document.write( "Similarly, we know q = 3. So you replace all copies of q with 3.
\n" ); document.write( "After that, you evaluate using PEMDAS\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "|p| - |3q|\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "|-2| - |3q|\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "|-2| - |3(3)|\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "|-2| - |9|\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2 - 9\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-7\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, |-2| - |3(3)| = -7\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and, |p| - |3q| = -7 when p = -2 and q = 3 \n" ); document.write( "

\n" );
