Guys Help, Im not sure if it's A or D 2. Use an augmented matrix to solve the system. What is the value of x and y? x + y = 5 3x – y = –1 (1 point) (1, 4) (1, 5) (3, –1) (5, –1)

    The answer is A, Whenever you are confused or not sure, you can always try to put the values of x and y in the both equations and verify your ans. A satisfies the both eqns but D doesn't!

    This is not the actual method, but its a trick to verify your ans or solve multiple choice questions.
