Recorda que <br />- si rangA = rangA* = nombre d'incògnites = #n, el sistema és compatible determinat <br />- si rangA = rangA* < nombre d'incògnites = #n, el sistema és compatible indeterminat<br />- si rangA <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mo»§#8800;«/mo»«/math»</span>rangA* , el sistema és incompatible<br /><br />En aquest cas, rang(A)=#rA i rang(A*)=#rAamp<br />
