# Cramer's Rule Calculator

Cramer's rule is used to solve a linear system of 2x2 equations, when it has a unique solution. However, it is not suitable for more than 2 or 3 equations. It was introduced by Gabriel Cramer and hence the name was derived. He was the one who introduced a rule for an arbitrary number of unknowns. This calculator is used to solve a 2x2 system of equations.
