Algebra.Com's Answer #316299 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! Just substitute x = 1, y = 8.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2(1) + 6(8) = 50 (true)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "10(1) + 8(0) = 50 (true)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So (1,8) is a solution to the system (also, the only solution). \n" ); document.write( " |
