To solve the system of linear equations using Cramer's rule, we first need to find the determinants of the coefficient matrix and the matrices obtained by replacing the x-column with the constants and the y-column with the constants.
The coefficient matrix is: | 1 1 | | 2 -3 |
The determinant of the coefficient matrix (denoted as D) is: D = (1)(-3) - (2)(1) = -3 - 2 = -5
Now, we replace the x-column with the constants: | 6 1 | | -2 -3 |
The determinant of this matrix (denoted as Dx) is: Dx = (6)(-3) - (-2)(1) = -18 + 2 = -16
Next, we replace the y-column with the constants: | 1 6 | | 2 -2 |
The determinant of this matrix (denoted as Dy) is: Dy = (1)(-2) - (2)(6) = -2 - 12 = -14
Now, we can find the values of x and y using Cramer's rule: x = Dx / D = -16 / -5 = 16/5 y = Dy / D = -14 / -5 = 14/5
Therefore, the solution to the system of linear equations is x = 16/5 and y = 14/5.
