Problem 2. Consider the linear system ax₁ + bx₂ cx₁ + dx₂ = j = k, where a, b, c, d, j, k are real numbers. (a) Choose specific values of a, b, c, d for which ad-bc = 0 and show by example that you can find values of j, k for that make the system consistent and other values of j, k that make the system inconsistent. (b) Consider again the above system, but now a, b, c, d are any real numbers for which ad-bc= 0. Explain why it's always possible to find values of j,k for which the system is inconsistent.
