Cramer’s Rule Steps

1. turn the system of equations into a matrix

2. find the determinant of just this matrix and call it D

3. remove the x column and replace it with the constants

4. find the determinant of this matrix and call it Dx

5. remove the y column and replace it with the constants

6. find the determinant of this matrix and call it Dy

7. repeat this for any additional variables (Dz, Da, Db, etc.)

8. solve for x, y, and so on using x = Dx / D and y = Dy / D and so on
