Webb1 Write the simultaneous equations as a matrix equation in the form AX = B. Matrix A is the matrix of the coefficients of x and y in the simultaneous equations, X is the matrix of the β¦ WebbMarketing. This article will show you the methods to solve simultaneous equations using two algebraic techniques (elimination and substitution) and graphically solve simultaneous equations. We will also teach you to inspect the number of possible solutions to an equation without needing to solve it, by interpreting graphs.

WebbExample 3: Solving a Set of Simultaneous Equations Using Matrices Consider the system of equations 2 π + 2 π + 4 π = 4, β π β π β π = 1 4, 2 π + 5 π + 6 π = 1 0. Express the system as a single matrix equation. Work out the inverse of the coefficient matrix. Multiply through by the inverse, on the left-hand side, to solve the matrix equation. Answer Webb1. Using the inverse matrix on a system of two equations If we have one linear equation ax = b in which the unknown is x and a and b are constants then there are just three possibilities β’ a =0then x = b a β‘ aβ1b.The equation ax = b has a unique solution for x. β’ a =0,b =0then the equation ax = b becomes 0 = 0 and any value of x will do.
