Observe that the second column is the sum of the first and third columns. Find a nontrivial solution of Axequals0 without performing row operations. [Hint: Write Upper A Bold x equals Bold 0 as a vector equation.]xequalsnothing

Think of A = [ a1 a2 a3 ].

The text points out that a1 + a3 = a2.

Rewrite this as a1 -a2 + a3 = 0.

As a matrix equation, Ax = 0 for x = (1, -1, 1).
