SOLVING EQUATIONS BY DETERMINANTS - CRAMER'S RULE

If the number of equations is more than two, it is easier to get the solution by using determinants.

If I1, I2 and I3 are the three unknowns in a system of three linear equations

Then, the system can be written in matrix form as follows:

The values of I1, I2 and I3 are given by

This is known as Cramer's rule and can be applied to any system of n linear equations provided Δ is not zero.
