WebCramer’s Rule for 2×2 Systems. Cramer’s Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables. Consider a system of two linear equations in two variables. a1x + b1y = c1 a2x + b2y = c2. The solution using Cramer’s Rule is given as.
