9. Variation of Cramer’s Rule by Babarinsa Olayiwola Isaac - Volume28, No. 2, (November, 2014), pp 57 – 60
Sale price: $5.00

Cramer’s rule has been known for decades to solve system of linear equation yet
it does not provide all information needed. The deficiency of the formula is addressed in the variation by focusing on the coefficients and constants of the system. The true value of the constants of the system is revealed by adding the initial constant of the system to sum of the coefficients of the unknown variables in corresponding to each equation. Generally, the known formula and the variation produce the same result but the variation ensures that the coefficients of the variables are unified.
