We have been given a system of equations and we are asked to write correct coefficient matrix for this system.
Since we know that a matrix for a system of equations is in the form: , where A represents the coefficient matrix, X is variables''s matrix and B is the constant matrix.
We are given two equation and two unknown variables, so our coefficient matrix will be a matrix. Our matrices for variable and constant will be of dimensions
(column matrix).
We can represent our given system of equations in matrix form as:
Now let us find our A, X and B parts from above matrices.
Since we know that A represents coefficient matrix, therefore, correct coefficient matrix for our system of equations will be,
