Apples & Oranges - Algebra
Adding Apples and Oranges Version with 1 decimal

This new application is a basic tool to learn algebra.
Trying solving a system of linear equations with two equations and two unknown variables. (Two purchases)
Based on the same problem seen at the free "Adding Apples and Oranges." (https://play.google.com/store/apps/detai...andoranges) where only used integers.
Now, this new program works externally with a decimal.

It contains:

. A button that generates new questions ("two new purchases of fruits").
. Two drop-downs to select a solution and a button to verify: The verification button checks the solution, and adds it to the list of the session.

You can edit the statements. The program checks if the determinant of the proposed statement is nonzero.
