Which solution method?
\n" ); document.write( "I'll use elimination.
\n" ); document.write( "Multiply eq. 1 by 5 and add the two equations together.
\n" ); document.write( " $\"25m%2B5n%2Bm-5n=35%2B43\"$
\n" ); document.write( " $\"26m=78\"$
\n" ); document.write( " $\"highlight%28m=3%29\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"5m%2Bn=7\"$
\n" ); document.write( " $\"5%283%29%2Bn=7\"$
\n" ); document.write( " $\"15%2Bn=7\"$
\n" ); document.write( " $\"highlight%28n=-8%29\"$ \n" ); document.write( "

\n" );
