\"P=a%2Bb%2Bc\" Start with the given equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P-a-b=c\" Subtract \"a\" from both sides. Subtract \"b\" from both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is \"c=P-a-b\"
