Rules of simultaneous equations

WebbSolve 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 Webbsolve simultaneous linear equations using straight line graphs If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the …
