If there is no solution type "no solution" (without quotes) in each case. If there are many solutions. for a two parameter solution type Y in the Y = box and Z in the Z : box, and then give X in terms of Y and Z ; For a one parameter solution type Z in the Z : box and then give X and Y in terms of Z . For a three parameter solution type Z in the Z = box, type Y in the Y = box, and type Z in the Z : box. X : Your response Correct response No answer E :2??sz : Auto graded Grade: 0'10 0 i Y : _ Your response Correct response No answer L -3 : Auto graded Grade: 0/10 0 1 Z : 7 Your response Correct response No answer L 2 1 Auto graded Grade: 0l1.0 o 0 Total grade: 0.0x1l4 + 0.0x1l4 + 0.0x1f4 + 0.0x1i'4 = 0% + 0% + 0% + 0% Feedback: This system has multiple solutions. We can see this using a variety of methods. One method is to form the 3x4 matrix of coefficients, where the first 3x3 matrix represents the coefficients on the variables X , Y and Z , and the fourth column represents the constant terms. The first row of the 3x4 matrix contains the coefficients and the constant term from the first equation, the second row of the contains the coefficients and the constant term from the second equation and so on. Our matrix should look like this: 1 O 2 2 2 1 e4 *7 ,2 ,2 4 10
