Algebra.Com's Answer #50740 by piglet162431(90) ![]() You can put this solution on YOUR website! first of all, this is not a inequality problem! [=\r \n" ); document.write( "\n" ); document.write( "Well, we can simply plug the coordinates back in to check. \n" ); document.write( "(9,-2), x is 9, y is -2... \n" ); document.write( "soo \n" ); document.write( "2x+3y=127 is \n" ); document.write( "2(9)+3(-2)=127 \n" ); document.write( "18-6=127 \n" ); document.write( "12 does not equal to 127!\r \n" ); document.write( "\n" ); document.write( "there fore (9,-2) is not a solution of 2x+3y=127 \n" ); document.write( " |
