Solve for x:
\n" ); document.write( "\"a%2F3+=+x%2F21\" Multiply both sides by 3.\r
\n" ); document.write( "\n" ); document.write( "\"a+=+3x%2F21\" Multiply both sides by 21.
\n" ); document.write( "\"21a+=+3x\" Finally, divide both sides by 3.
\n" ); document.write( "\"7a+=+x\"
\n" ); document.write( "
\n" );
