Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the following augmented matrix: [[1, 2, 3, 5], [2, 4, 6, 10]], analyze its rank and determine if the system is consistent and whether it has a unique solution.

💡 Hint: Inspect the rows for linear dependency.

Challenge 2 Hard

For a system defined by a 4x4 matrix where three rows are linearly independent, determine what types of solutions are possible given three variables.

💡 Hint: Think about how many dimensions are represented versus how much freedom there is in choosing solutions.
