This is NOT as COMPLEX as the other \"respondents\" make it seem! \r\n" );
document.write( "EASISET/QUICKEST/LEAST TIME-CONSUMING method, as follows: \r\n" );
document.write( "\r\n" );
document.write( " x - 2y +  z = - 3 ------ eq (i)\r\n" );
document.write( "      y + 2z = - 5 ------ eq (ii)\r\n" );
document.write( " x +  y + 3z = - 6 ------ eq (iii)\r\n" );
document.write( "     3y + 2z = - 3 ------ Subtracting eq (i) from eq (iii) ------ eq (iv)\r\n" );
document.write( "2y = 2 ------- Subtracting eq (ii) from eq (iv)\r\n" );

document.write( "1 + 2z = - 5 ------- Substituting 1 for y in eq (ii)\r\n" );
document.write( "2z = - 5 - 1\r\n" );
