WebThe third column does not contain a pivot, so x 3 is an independent variable. Therefore, there are infinitely many solutions for x 1 and x 2, and x 3 can be chosen freely. x 1 = 2 - 3 x 3 x 2 = 4 - 2 x 3. For example, if x 3 = 1, then x 1 = - 1 and x 2 = 2. WebIf there are 7 pivots (a pivot in every row), then A will span R 7 . However, since A has only 4 columns, it is not possible to have more than 4 pivots. 7. (a) The columns of B are linearly dependent regardless of the number of pivots. B must have 8 pivots in order for its columns to be linearly independent (a pivot in every column).
