Challenge Problems
Push your limits with challenges.
Question 1
A system of three equations is given. Identify its consistency: 2x + 3y + z = 6, x - y + 2z = 3, 4x + 6y + 2z = 12. Is it consistent or inconsistent?
💡 Hint: Think about how one equation can be derived from another; this implies dependence.
Question 2
