Linear equations to matrix
NettetThe phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is the graph of the function of x that has been defined in the preceding section. If b = 0, the line is a vertical line (that is a line parallel to ... NettetSolve a system of two equations using Cramer’s rule. Step 1. Evaluate the determinant D, using the coefficients of the variables. Step 2. Evaluate the determinant D x. Use the constants in place of the x coefficients. Step 3. Evaluate the determinant D y. Use the constants in place of the y coefficients. Step 4. Find x and y. x = D x D, y = D y D
