\r\n" );
document.write( "The way to find out is to plug in (2) for x and (0) for y\r\n" );
document.write( "the simplify to see if both equations come out with the  \r\n" );
document.write( "same number on both sides of the equation.\r\n" );

\r\n" );
document.write( "We'll plug in (2) for x and (0) for y:\r\n" );

document.write( "Yes, (2,0) is a solution because when we plugged in (2) for x and (0)\r\n" );
