SUMMARY
The discussion centers on solving a linear system to determine the distance at which the cost of renting a car from two agencies becomes equal. Rent-a-Heap charges \$50 per day plus \$0.12/km, while Kurt's Rent-a-Car charges \$40 per day plus \$0.20/km. The equation to find the distance (x) where costs are equal is derived from the linear equation format y = mx + b, leading to the formulation Ax + By = C. The solution involves setting the total costs equal and solving for x.
