\"4%2F5+=+64%2Fc\" Start with the given equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"c%284%2F5%29+=+64\" Multiply both sides by c\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4c+=+64%2A5\" Multiply both sides by 5\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4c+=+320\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"c+=+80\" Divide both sides by 4 to isolate c
\n" ); document.write( "
\n" );
