Given r = 9
\n" ); document.write( "\"4r+%2B+3s+=+75\"
\n" ); document.write( "Plug 9 into the equation for r
\n" ); document.write( "\"4%2A%289%29+%2B+3s+=+75\"
\n" ); document.write( "\"36+%2B+3s+=+75\"
\n" ); document.write( "Subtract 36 from both sides.
\n" ); document.write( "\"3s+=+39\"
\n" ); document.write( "Divide both sides by 3
\n" ); document.write( "\"highlight%28s+=+13%29\"
\n" ); document.write( "
\n" );
