Convert the system 3x1 5x2 -2 = 6x1 7x2 -1 to an augmented matrix. then reduce the system to echelon form and determine if the system is consistent. if the system in consistent, then find all solutions. augmented matrix: echelon form: is the system consistent? select ( solution: (x1, x2) = + + s1 : to enter a matrix use [[ 1. for example, to enter the 2 x 3 matrix 2 you would type [[1,2,,5,4]1, 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 before each s. for example, if the answer is (x, x2)= (5,-2), then you would enter (5 +0s1,-2 + 0s1). if the system is inconsistent, you do not have to type anything in the "solution" answer blanks. i
