Problem 6. (1 point) Find all solutions to the system 4x1 3x1 by eliminating one of the variables. + 3x2 4x2 = 2 = 14 Help: If there is a solution (a,b), enter your answer as a point (a,b). If there is a free variable in the solution, use s1 to denote the variable st. If there is no solution, type no solution. Answer(s) submitted: (incorrect) Problem 7. (1 point) Determine if the linear system -5x1 3x2 = 7 9x2 = 0 is in echelon form. First choose which of the following statements are correct. If there is more than one reason why the system is not in echelon form. type the letters as a comma separated list. If the system is in ech- elon form, make sure to type D as your answer. A. The system is not in echelon form because a variable is the leading variable of two or more equations. B. The system is not in echelon form because the system is not organized in a descending "stair step" pattern so that the index of the leading variables increases from the top to bottom. C. The system is not in echelon form because not every equation has a leading variable. D. The system is in echelon form. Correct Letter(s):. If the system is in echelon form, also identify the leading variables and the free variables in the corresponding answer blanks below. Type x1 and x2 to enter the variables x, and x₂ and separate mul- tiple variables by using a comma. If the system is in echelon form and no such variable exist, type none. If the system is not in ech- elon form, type NA in both answer blanks, Leading variable(s):
