You can put this solution on YOUR website!
These equations have already been reduced, so all you need to do is combine them in a way that eliminates either the X's or Y's. Notice that #1 has a +y, while #2 has a -y. Those will cancel each other out when added together. So just add the two together.
\n" ); document.write( "\"2x+%2B+y+=+5\"
\n" ); document.write( "\"x+-+y+=+1\"
\n" ); document.write( "becomes
\n" ); document.write( "\"3x%2B0y=6\"
\n" ); document.write( "\"3x=6\"
\n" ); document.write( "\"x=2\"
\n" ); document.write( ".
\n" ); document.write( "Then just plug into the easier original equation.
\n" ); document.write( "2)\"2x%2By=5\"
\n" ); document.write( "\"2%282%29%2By=5\"
\n" ); document.write( "\"4%2By=5\"
\n" ); document.write( "\"y=5-4=1\"
\n" ); document.write( ".
\n" ); document.write( "Therefore, x=2 and y=1. Hope this helps!
