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( "
\n" );
