You can put this solution on YOUR website!
2x - y = 8
\n" ); document.write( "x + 4y = 13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%282x=y%2B8%2C2x=-8y%2B26%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y%2B8=-8y%2B26\" by equating the two expressions\r
\n" ); document.write( "\n" ); document.write( "\"9y=26-8\"\r
\n" ); document.write( "\n" ); document.write( "\"9y=18\"\r
\n" ); document.write( "\n" ); document.write( "\"y=2\" and find x from there, however you want.
\n" ); document.write( "
\n" );
