Linear Equations is a free Android app developed by Peter Ho that allows users to easily calculate linear equations. This app is designed to solve 2 and 3 linear equations, and it also offers the option to load and save linear equations from and to a CSV file.

In addition, the PRO version of the app provides a wider range of features, including the ability to solve 3 to 9 linear equations and an ad-free experience. However, this version comes at a cost.

It is important to note that the developer encourages users to email him for support rather than using the feedback section of the app.
