Use Cramer's rule to find the values of the variables x, y, and z (3 points each). Show the determinants involved clearly and expand the numerator determinants as follows to get any credit: For variable x, expand along the first column; for variable y, expand along the second column; for variable z, expand along the third column. You will receive 0 points if you expand these determinants any other way, even if your answer is correct. -3x + (0)y-6 = 11 (6)x2y+ 3 = 17 2x -y (8)z = -3
