A percent is a number multiplied by 100.
\n" ); document.write( "So 30% can also be written as $\"30%2F100\"$
\n" ); document.write( "---------------
\n" ); document.write( "Lets write our equation.
\n" ); document.write( " $\"X+-+%2830%2F100%29%2AX+=+126\"$
\n" ); document.write( "Simplify
\n" ); document.write( " $\"X+-+0.3%2AX+=+126\"$
\n" ); document.write( "Combine like terms
\n" ); document.write( " $\"0.7X+=+126\"$
\n" ); document.write( "Divide both sides by 0.7
\n" ); document.write( " $\"highlight%28X+=+180%29\"$ \n" ); document.write( "

\n" );
