Subtract eq. 1 from eq. 2,
\n" ); document.write( " $\"8x-y-%287x-y%29=47-39\"$
\n" ); document.write( " $\"8x-y-7x%2By=8\"$
\n" ); document.write( " $\"x=8\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"7%288%29-y=39\"$
\n" ); document.write( " $\"y=56-39\"$
\n" ); document.write( " $\"y=17\"$ \n" ); document.write( "
