i dont understand it.

check out this page http://marc.mtsac.edu/worksheet/general_topics/7cramer_rule.pdf

Well thats dandy and all but i just don't see where any of these would equal no solution.

jim_thompson5910 · Answer

look in the section where it says "If the determinant in the denominator is zero, then one of two things is implied"

anonymous · Answer

Wouldn't there still be a solution though?

jim_thompson5910 · Answer

there's only a solution (infinitely many actually) when all 3 determinants D, Dx, Dy are all zero

jim_thompson5910 · Answer

If D = 0, but Dx and Dy are nonzero, then you'll have an inconsistent system (ie no solutions)

anonymous · Answer

oh ok so as long as a numerator isn't zero and the denominator is zero it will be inconsistent

thx
