Can this be explained by use of one solution, no solution or infinitely many solutions? If not, just summarize it for me the way you understand it. Sent from my SMG955W using Tapatalk Last edited by skipjack; December 8th, 2017 at 10:08 AM.

What is "this"?

It is not clear (to me) what sort of equations are we looking at?

First if a set of linear equations is "independent", that is, each vectors whose components are the coefficients of the same unknown are independent (equivalently the matrix of coefficients has nonzero determinant), then there must be exactly one solution and vice versa. If the system of equations is NOT independent, then there may be no solution or an infinite number of solutions. Conversely, if a system of linear equations has either no solution or an infinite number of solutions then the equation are "dependent". Is that what you mean?
