Numbers x and y follow through your description to give this system:
\n" ); document.write( "\"system%28xy=-110%2Cx%2By=-30%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=-x-30\"
\n" ); document.write( "-
\n" ); document.write( "\"x%28-x-30%29=-110\"
\n" ); document.write( "\"-x%5E2-30x=-110\"
\n" ); document.write( "\"x%5E2%2B30x=110\"
\n" ); document.write( "\"x%5E2%2B30x-110=0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Discriminant: \"30%5E2-4%2A1%2A%28-110%29=900%2B440=1340\"
\n" ); document.write( "which is \"2%2A67%2A2%2A5=2%2A2%2A5%2A67\";\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight%28x=%28-30%2B-+2sqrt%285%2A67%29%29%2F2%29\"
\n" ); document.write( "You can find the y value corresponding to each of these x values.
\n" ); document.write( "
\n" );
