1. $\"9m+%2B+n+=+13\"$
\n" ); document.write( "2. $\"m-9n=47\"$
\n" ); document.write( "Multiply eq. 1 by 9 and add to eq. 2 to eliminate $\"n\"$ and solve for $\"m\"$ .
\n" ); document.write( " $\"81m%2B9n%2Bm-9n=117%2B47\"$
\n" ); document.write( " $\"82m=164\"$
\n" ); document.write( " $\"highlight%28m=2%29\"$
\n" ); document.write( "Then use either equation to solve for $\"n\"$ .
\n" ); document.write( " $\"9%282%29%2Bn=13\"$
\n" ); document.write( " $\"18%2Bn=13\"$
\n" ); document.write( " $\"highlight%28n=-5%29\"$
\n" ); document.write( " \n" ); document.write( "
