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

You need to find detA first, of matrix%283%2C3%2C%0D%0A2%2C3%2C-1%2C%0D%0A1%2C+-3%2C2%2C%0D%0A3%2C1%2C1%29

then find the det of matrix%283%2C3%2C%0D%0A35%2C3%2C-1%2C%0D%0A-8%2C+-3%2C2%2C%0D%0A36%2C1%2C1%29

then find the det of matrix%283%2C3%2C%0D%0A2%2C35%2C-1%2C%0D%0A1%2C-8%2C2%2C%0D%0A3%2C36%2C1%29

then find the det of matrix%283%2C3%2C%0D%0A2%2C3%2C35%2C%0D%0A1%2C+-3%2C-8%2C%0D%0A3%2C1%2C36%29
