1 point) Convert the system 21 + 9x2 x1 + 4x2 -44 -20 o an augmented matrix. Then transform the system to reduced echelon form and determine if the system is consistent. If the system is consistent, then find all olutions. Lugmented matrix: Reduced echelon form: the system consistent? select + $1 olution: (1,2)= + $1 lelp: To enter a matrix use [[],[]]. For example, to enter the 2 3 matrix 1 2 3 6 5 4 ou would type [[1,2,3],[6,5,4]], so each inside set of [] represents a row. If there is no free variable in the solution, then type 0 in each of the answer blanks directly
