\n" ); document.write( "1. $\"X%2BY=60\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"1%28X%29%2B10%28Y%29=3%2860%29\"$
\n" ); document.write( "2. $\"X%2B10Y=180\"$
\n" ); document.write( "Subtract eq. 1 from eq. 2,
\n" ); document.write( " $\"X%2B10Y-X-Y=180-60\"$
\n" ); document.write( " $\"9Y=120\"$
\n" ); document.write( " $\"Y=40%2F3\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"X%2B40%2F3=60\"$
\n" ); document.write( " $\"X=180%2F3-40%2F3\"$
