Method of Determinants is considered as an easier solution when you have more than two equations to solve:
Where I1, I2 and I3 are the unknown, we need to solve the equation for.
We can calculate the value of the unknowns, I1, I2 and I3 by the following matrix calculation:
Considering the value of △ as a non-zero figure, this rule can be applied to any system that has n number of linear equations. This rule is known as Cramer’s Rule.
