Solve the system of equations:
\n" ); document.write( "\"system%28x%2B2y=8%2C%0D%0Ax=9-2y%29\"
\n" ); document.write( "
\r\n" );
document.write( "Substitute \"%289-2y%29\" for x in\r\n" );
document.write( "\r\n" );
document.write( "\"x%2B2y=8\"\r\n" );
document.write( "\r\n" );
document.write( "\"%289-2y%29%2B2y=8\"\r\n" );
document.write( "\r\n" );
document.write( "\"9-2y%2B2y=8\"\r\n" );
document.write( "\r\n" );
document.write( "\"9-cross%282y%29%2Bcross%282y%29=8\"\r\n" );
document.write( "\r\n" );
document.write( "\"9=8\"\r\n" );
document.write( "\r\n" );
document.write( "That's a false numerical equation, so the\r\n" );
document.write( "system is inconsistent.  So if you graph both\r\n" );
document.write( "equations by plotting points, you get these two \r\n" );
document.write( "parallel lines below, which will never intersect \r\n" );
document.write( "and so there is no common solution to both \r\n" );
document.write( "equations:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
