Explanation Given Information: The provided systems of equations are: 2 x + y = 7 and − x = 9 Formula Used: Converting system of equations to matrix equation: Let A X = B is a matrix equation, where X is the matrix containing the variable terms. So, the coefficient of matrix A has entries equal to the coefficients of the left-hand sides of the equations. Calculation: Consider the provided system of equations: 2 x + y = 7 and − x = 9 Use the mentioned formula which states that the coefficient of matrix A has entries equal to the coefficients of the left-hand sides of the equations. Separate the coefficients from the provided system of equations as: ( 2 ) x + ( 1 ) y = 7 and ( − 1 ) x + ( 0 ) y = 9 Now, matrix A is obtained as: [
