(1) \"+m+%2B+n+=+10+\"
\n" ); document.write( "(2) \"+3m+-+2n+=+15+\"
\n" ); document.write( "-------------------
\n" ); document.write( "(1) \"+n+=+10+-+m+\"
\n" ); document.write( "Substitute this result into (2)
\n" ); document.write( "(2) \"+3m+-+2%2A%28+10+-+m+%29+=+15+\"
\n" ); document.write( "(2) \"+3m+-+20+%2B+2m+=+15+\"
\n" ); document.write( "(2) \"+5m+-+20+=+15+\"
\n" ); document.write( "(2) \"+5m+=+35+\"
\n" ); document.write( "(2) \"+m+=+7+\"
\n" ); document.write( "and, since
\n" ); document.write( "(1) \"+m+%2B+n+=+10+\"
\n" ); document.write( "(1) \"+7+%2B+n+=+10+\"
\n" ); document.write( "(1) \"+n+=+3+\"
\n" ); document.write( "-------------
\n" ); document.write( "check:
\n" ); document.write( "3 times the larger is 21
\n" ); document.write( "twice the smaller is 6
\n" ); document.write( "\"+21+-+6+=+15+\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" ); document.write( "
\n" );
