You can put this solution on YOUR website!

document.write( "2x - y =   8 ----- eq (i)\r\n" );
document.write( " x + 4y = 13 ----- eq (ii)\r\n" );
document.write( "\r\n" );
document.write( "Again, this is a real LAUGH! Equation 1 can be easily solved for y, since the coefficient on y is - 1. Likewise, \r\n" );
document.write( "eq (ii) can be easily solved for x, as too has a coefficient of 1 on x. \r\n" );

document.write( "So, why on earth would someone choose to SOLVE for a variable that has created FRACTIONS - which most people hate,\r\n" );
document.write( "and which we normally GET RID OF when solving an equation - when 2 perfectly-stated equations (i) & (ii), already have variables\r\n" );
document.write( "with coefficients - 1 and 1? This ABSOLUTELY makes NO SENSE, at all!!! \r\n" );
document.write( "\r\n" );

document.write( "This may be one of the reasons why some people FEAR mathematics! I would, if I ever asked for help, and received this response!!
