How Do I Solve a System with Inverses Using WolframAlpha?

In the handout

  • Handout: Solve a System with Inverses

I showed you how to find the inverse of a coefficient matrix. I also showed how to used it to solve the system

5x + 7y + 12z = 134,000
2x + 3y + 5z = 56,000
x + y + z = 14,000

In this post, I want to show you how to solve this system using WolframAlpha.
