Course: Elementary Algebra
Topic: Linear Systems
Subtopic: Applications


In real world problems there are often several constraints (conditions on the variables) that need to be met simultaneously. For instance when designing a plane at Boeing the engineers typically work with systems containing 140,000 equations in 140,000 variables! (Thank goodness for technology, aye?)

The applications on which we will concentrate here are mostly mixture problems meaning that two or more things (nuts, coffees, etc.) are being mixed together. When translating them into a linear system, look for the "quantity * quality" relationship as it will help you to form the equations.


By the end of this topic you should know and be prepared to be tested on:


Terms you should be able to define: mixture problem, quantity and quality (in terms of mixture problems)
