Question 201959
First, construct the augmented matrix by writing the coefficients and right hand constants:


{{{ (matrix(3,4,1,-1,11,4,0,1,2,1,3,1,-13)) }}}



Now let's perform row reductions to determine whether the system is independent, dependent, or inconsistent (solution provided by the <a href="http://www.math.odu.edu/~bogacki/lat/">Linear Algebra Toolkit</a>)

From the last matrix, we can see that there is a value of 1 in every pivot position. So this means that there is a unique solution, which means that the system is independent.



So the answer is C) Independent
