This equation may be easily reduced to an equation of Rriccarr. 
For adding up, in the first determinant the third column multiplied 
by 4, to the fifth and in the second determinant the second and 
third columns each multiplied by 4, to the fourth and last, we get

If we in the same way subtract the fifth column multiplied by Ss 
from the third, the numerator takes the form
