You can put this solution on YOUR website!
Here we must simply plug y=2x-6 into the second equation. We get:\r
\n" ); document.write( "\n" ); document.write( "\"2x%2By=6\"
\n" ); document.write( "\"2x%2B2x-6=6\"
\n" ); document.write( "\"4x=6%2B6=12\"
\n" ); document.write( "\"x=3\"\r
\n" ); document.write( "\n" ); document.write( "Now we plug x=3 into the first equation, getting that y=0.
\n" ); document.write( "
\n" ); document.write( "
\n" );
