Example 3.25 uses the inverse of the coefficient matrix to solve a linear system. This method can be used to solve the following system. X- x2 = 1 9x1 + x2 = 9 State the coefficient matrix A. (Order the columns from x, to x2 Do not perform any row operations.) A = Find the inverse of the coefficient matrix. A-1 = Give b such that Ax = b. b= Solve the given system using the method of Example 3.25.
