Question: matrix dimension is not correct i need help with that...

Question details

(1 point) Given that the matrix 7 4 0 2 10 7-1 7-2 7 is the augmented matrix for a linear system, use technology to perform the row operations needed to transform the matrix to reduced echelon form. Then determine if the system is consistent and if it is, find all solutions to the system. Reduced echelon form: 1-7,4.0,2.101(0-43.35,-39,139),(0.0.126.23,586m Is the system consistent? yes # Solution: (x1-X2, x3,x4) = (1158/E | + |-206|$1,1629|+|-19/1 |sn]283/E1+1-23/1 | $1.10-1 Help: To enter a matrix use Dil]. For example, to en er the 2 × 3 matrix 131 3 you would type [1,2,3],[6,5,41, so each inside set of [1 represents a row. If there is no free variable in the solution, then type 0 in each of the answer blanks directly before each s1 For example, if the answer is (xi, xz.x3) (5,-2, 1), then you would enter (5 + 0s1+-2 + 0sı , 1 + 0si ). İf the systern is inconsistent, you do not have to type anything in the Souton, answer blanks. Note: You can earn partial credit on this problem
