Mutliply eq. 2 by 5 and add to eq. 1,
\n" ); document.write( " $\"7x%2B10y%2B%2815x-10y%29=-13%2B35\"$
\n" ); document.write( " $\"22x=22\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"3x-2y=7\"$
\n" ); document.write( " $\"3%281%29-2y=7\"$
\n" ); document.write( " $\"3-2y=7\"$
\n" ); document.write( " $\"-2y=4\"$
\n" ); document.write( " $\"y=-2\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
