Solving a system of equations by using matrices is merely an organized manner of using the elimination method.

Systems of linear equations one of the most important problems in technical computing is the solution of systems of simultaneous linear equations in matrix. If in an equation, a variable stands in a matrix form, then that equation is known as matrix equation we can solve such type of equations using the following operations. Can be written as a matrix equation ax~ = ~b let a be the matrix of coeﬃcients aij, let x~ be the column vector of variable names x1 52 matrix equations 271. Matrix equations this chapter consists of 3 example problems of how to use a “matrix equa-tion” to solve a system of three linear equations in three variables.
