Hints:

Be sure you understand the three methods of solving a system of N linear equations: by ‘brute force’ or substitution; by finding the inverse of the matrix of coefficients; and by using determinants as per Cramer’s Rule. Because the exam has limited time, you should go through the examples in the textbooks, and practice how to find the solution.

The exam question sheets should not be turned in with your blue books. The questions are useful for class discussion, so please bring them with you for the class meetings after the exam.

Relax. It’s only math. It’s only economics. It’s not the beginning or the end of the world.
