A system of linear equations is consistent if it has at least one solution. Check the last non-zero row of the augmented matrix in row echelon form: If it is of the form (0,…,0,*), where * is nonzero, then the system has no solution (not consistent). Otherwise, the system is...

system of linear equations, underlying the deep connections of linear algebra. We then introduce the notion of a matrix as a function on vectors. Questions now about properties of the matrix as a function also turn out to be answered by solving a linear system. These connections between ...
Systems of linear equations over a field K can be solved by various methods, e.g., by Gaussian elimination or Cramer's rule. But if we start with a system over the integers, we will immediately introduce rational numbers, whose arithmetic operations are clearly more costly than the ...
A system of linear equations need not have a solution. We have already talked about it in vector notation. Here is another example: there do not exist numbers x and y making the following two equations true simultaneously:{x+2y=4−3x−6y=7{x+2y=4−3x−6y=7In this case, the ...
