\n" ); document.write( "m+3n= 2
\n" ); document.write( "m=2-3n
\n" ); document.write( "3(2-3n)-6n=1
\n" ); document.write( "6-9n-6n=1
\n" ); document.write( "6-15n=1
\n" ); document.write( "5=15n
\n" ); document.write( "5/15=n
\n" ); document.write( "1/3=n
\n" ); document.write( "m+3*(1/3)= 2
\n" ); document.write( "m+1=2
