Question 28601
i think i have just answered your other question on Cramer's rule.


You need to find detA first, of {{{matrix(3,3,
2,3,-1,
1, -3,2,
3,1,1)}}}


then find the det of {{{matrix(3,3,
35,3,-1,
-8, -3,2,
36,1,1)}}}


then find the det of {{{matrix(3,3,
2,35,-1,
1,-8,2,
3,36,1)}}}


then find the det of {{{matrix(3,3,
2,3,35,
1, -3,-8,
3,1,36)}}}
