If you only check selectively, which kind of answers do you usually check?<br /><br />How do you do your checking? Can you think of a faster way to do the checks?<br /><br /><span style="font-size:78%;">[Habits of Mind: Striving for Accuracy]</span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3286611060008064223-3975890702638892128?l=simultaneouslinearequations.blogspot.com' alt='' /></div>Mrs Taufiq-Kris Ngnoreply@blogger.com5tag:blogger.com,1999:blog-3286611060008064223.post-28630193223130876172009-03-05T01:05:00.000-08:002009-03-23T04:33:10.626-07:00<a href="http://4.bp.blogspot.com/_KhqYgSuRzCs/Sa-7N-rbGiI/AAAAAAAAAAU/YibJXq27Gp8/s1600-h/Graph1.jpg"><img id="BLOGGER_PHOTO_ID_5309668334530927138" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 300px; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_KhqYgSuRzCs/Sa-7N-rbGiI/AAAAAAAAAAU/YibJXq27Gp8/s400/Graph1.jpg" border="0" /></a><br /><div><br /><br /><div>Why is it that the intersection point is the answer to the simultaneous linear equations?
