Craimer's rule
Example
-
-
-
-
-
The answer for (x, y, z) is (−4, 2, 1).
-
Second, the matrix for the denominator for both the x and the y are the same
-
-
Third, you should find the numerator of both the x and the y, and this time, they're not the same.
To find the numerator of the x, for the first column of the matrix, place the numbers the come after the "=" sign, and for the second column, place the numbers with y/before the "=" sign.
To find the numerator of the y, the first column will be the numbers with x, while the second column will contain numbers that arrive after the "=" sign.
First, you must prepare a fraction for both the x and y
Fourth, simplify the fractions of both x and y and find the final answer
