Start with 100 equations Ax= 0 for 100 unknowns x = (x1, ... ,x100). Suppose elimination reduces the 100th equation to O = 0, so the system is "singular".(a) Elimination takes linear combinations of the rows. So this singular system has the singular property: Some linear combination of the 100 rows is ___.(b) Singular systems Ax = 0 have infinitely many solutions. This means that some linear combination of the 100 columns is(c) Invent a 100 by 100 singular matrix with no zero entries.(d) For your matrix, describe in words the row picture and the column picture of Ax = 0.
