3x-2y=5/2 ; 1/3x + 3y = -4/3. Solve using Cranmer's method. Please Provide explanation.

Equations are
3x - 2y = 5/2 , 1/3 x + 3y = -4/3
or we can write
6x - 4y = 5 , x + 9y = -4
Using Cramer's rule to find the values of x and y, there are 3 different values that we need to calculate, they are D, Dx, and Dy. In all 3 cases the “D” stands for the determinant
D = Determinant of x and y values in 2 x 2 matrix
x = Dx/D and y = Dy/D, here we replace x and y values with the values after the equal sign respectively
So we have,
D = [ 6 -4
1 9 ]
So D = (6)(9) - (-4)(1) = 58
Dx = [ 5 -4
-4 9 ]
So Dx = (5)(9) - (-4)(-4) = 29
Dy = [ 6 5
1 -4 ]
So Dy = (6)(-4) - (5)(1) = -29
Putting these values in our rule we get
x = 29/58 = 1/2
y = -29/58 = -1/2
