Add the two equations together to eliminate y,
\n" ); document.write( " $\"x%2By%2Bx-y=2b%2B2a\"$
\n" ); document.write( " $\"2x=2%28a%2Bb%29\"$
\n" ); document.write( " $\"x=a%2Bb\"$
\n" ); document.write( "Now find y,
\n" ); document.write( " $\"x%2By=2b\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"a%2Bb%2By=2b\"$
\n" ); document.write( " $\"y=2b-b-a\"$
\n" ); document.write( " $\"y=b-a\"$
\n" ); document.write( " \n" ); document.write( "
