The number in the first row, third column is wrong. It should be -3.667.

how is the determinant 3??? i thought it was 0? because to find the determinant you would have to do. 2(4)(3)+0(5)(3)+1(1)(1) which is 22 then that result minus 1(4)(3)+5(1)(2)+0(1)(3)= 22 so then 22-22=0

@purpler600

Try to calculate it another time:

2*4=8 *3= 24

0*5*3=0

1*1*1=1 = 25-22
