Let number of additional channels be C\r\n" );
document.write( "Then for plans to cost the same, we get: 2C + 45 = 3C + 30\r\n" );
document.write( "2C - 3C = 30 - 45\r\n" );
document.write( "    - C = - 15\r\n" );
document.write( "Number of additional channels to make both plans cost the same, or \r\n" );
document.write( "Substitute value of C into either side of the equation to get the cost!\r\n" );
document.write( "\r\n" );
document.write( "That's IT!! Could this be any simpler?
