Using Cramer's Rule, find the solution to the following system of linear equations: 3x + z = 2 – Y 2x + 2y + 5z = 1 x – z = 2+3y. 3. What is AA-1, where 2 2) A = 1 2 1 4. Find the area of the parallelogram with the points A(2,5, 6), B(4, 8, 10), C(11, 7, 9) and D(9, 4, 5) by using the cross product.
