SUMMARY
The discussion focuses on solving a system of equations to determine the amounts of two types of tea mixed to achieve a specific cost per kilogram. The cost of the first tea is 135kr/kg, while the second is 168kr/kg, and the desired mixture costs 150kr/kg. The correct system of equations is established as 135x + 168y = 150 and x + y = 1. A suggested method for solving this system involves substituting y with (1-x) in the first equation.
