1) For all problems below, consider the following matrices: 21 S=1 S = [] 4y Q= 3 = v = [1 - 32 % ] -2 -3 Perform the following calculations. Simplify terms where possible. If a calculation is not possible, state "Not Possible". Show your work and box your final answers. a) (2 pts) 2Q +35 b) (3 pts) 2VT - Q c) (3 pts) QU [4 17] 2. (7 points) Using previous question and let S+U = 2 Solve for x and y and express your final answer as an ordered pair (x, y). [Note: You should end up with a system of equations to be solved. You must use Gauss-Jordan Row Reduction to solve the system, showing all your work, in order to receive full credit. (you can check your work using calculator.]
