[header] How to use cramer's rule [title] Know the naming convention. [step] In a set of three equations, say 1 , 2 and 3, name the coefficients of the equation 1 as: a1, b1, c1. Name the constant term as d1.
Continue the correlations, while registering each coefficient in the equation. [substeps] For instance, the first coefficients of a1 and b1 are eliminated from the equation. If you define these as " theorems ", the answer will be printed on the notebook. With each variation, you solve the problem in the same way, with one variable representing another (b1, b2). Similarly, name the coefficients of equations 2 and 3 as: a2, b2, c2 and a3, b3, c3 with their constant terms being d2 and d3 respectively. [title] Arrange the coefficients in a 3x3 matrix named d. An answer based on the number of sub-equations equal to 4 and 2, g1. By placing the coefficients of the formula, write the coefficients on both sides of the equation.
