Solve the following linear system for x using Cramer’s rule.?
x + 2y – 3z = -22
2x – 6y + 8z = 74
-x – 2y + 4z = 29
Update:Could you explain this problem a little more? I just want to know how you get x?

Verified answer
x = det [-22 , 2 ,-3] divided by det [1 , 2 , -3]
........... [ 74 ,-6 , 8] ................. ...... [2, -6 , 8]
........... [ 29 ,-2 , 4] ................ ....... [-1,-2 , 4]
x = 3
similarly, replace the second column of the coefficient matrix by the constant column ...
y = -2
further, replace the third column of the coefficient matrix by the constant column
z = 7.
btw, the determinant of the coefficient matrix is -10.
