Subtract the first equation from the second to eliminate \"x\".
\n" ); document.write( "\"x%2B2y-x-y=0-1\"
\n" ); document.write( "\"y=-1\"
\n" ); document.write( "Then use either equation to solve for \"x\".
\n" ); document.write( "\"x-1=1\"
\n" ); document.write( "\"x=2\"
\n" ); document.write( "(2,-1)
\n" ); document.write( "
\n" );
