It is easy to see that the principal term in the amount of labor needed to solve a system of equations is kN3 in which N is the number of unknowns and k is a constant. Since an expert [human] computer requires about eight hours to solve a full set of eight equations in eight unknowns, k is about 1/64.

Finally, with respect to these top 5 equations, eq. (4) indicates that the right-hand-side will be 0 for each of them. Thus, we can now write down all elements in the first 5 rows of our matrix, as follows: Now we need to write the last 4 equations. These are the DC power flow equations corresponding to eq. (5).
