WebSuppose we have a system of n linear equations in m variables, and that the n m matrix A is the coe cient matrix of this system. Then 1.We have rank(A) n and rank(A) m, because there cannot be more pivots than there are rows, nor than there are columns. 2.If the system of equations is inconsistent, then rank(A) < n. This is because in row- WebAlgebraically, for such a case, a 1 /a 2 = b 1 /b 2 ≠ c 1 /c 2, and the pair of linear equations in two variables is said to be inconsistent.

Consistent and Inconsistent Linear Systems ( Read )

WebIf a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . WebA system is defined as inconsistent if its row-reduced echelon form contains a row of form [ 0 0 0... 0 k] where k ≠ 0 and is a separator within augmented matrix. Since your system equals 0 →, it is impossible to have k ≠ 0, rendering the system consistent.

Web"Inconsistent" is because it is not possible for both equations to hold simultaneously. They contradict each other in the sense that if one holds, the other must fail. Thus their graphs never intersect and there is no solution to their system. "Consistent" is then the opposite. … WebA linear system is consistent if and only if the coefficient matrix has the same rank as its augmented matrix (the coefficient matrix with an extra column added, that column being the column vector of constants). The augmented matrix has …
