Determine by inspection (i. e., without performing any calculations) whether a linear system with the given augmented matrix has a unique solution, infinitely many solutions, or no solution. 1 2 3 4 5 6 7 6 5 4 3 2 8 8 8 8 8 8

Infinitely Many Solutions

Step-by-step explanation:

Given

Required

Determine the type of solution

From the matrix, we have:

3 non-zero rows and 5 variables (the last column is the result)

When the number of variables is more than the number of non-zero rows, then such system has infinitely many solutions

i.e.

1. 22

2. 1

3. 7

4. 18
