Linear equation in 2 variables

Systems of linear equations in two variables app provide an easy way to help students to learn Algebra. Students can drag and drop or tap the numbers or variables of the equations to solve it. For example:students can click the numbers or variables to calculate it or drag and drop numbers,variables for substitution or Shift regulation.

In addition, this app use reverse thinking, built-random way to generate the questions, so any time you can have all the new questions to practice. Teachers can also use this app, ready to produce 20 exam questions, email them to print.

This app contains the following features:

1. Solving systems of linear equations in two variables - by elimination method
2. Solving systems of linear equations in two variables - by substitution method
More than two kinds of problem-solving methods, are using drag-and-click method, so students can easily learn of systems of linear equations.

3. Random generate Exam paper of system of linear equations and teacher can email it and print it out for students' Exam.

4. Solving systems of linear equations in two variables Calculator and graphing line function - students can input their own equations to calculate it and graphing the lines。

5. Solve by Graphing - the app will random give 2 equations and user can input the coordinates of the equations then the app will graphing the lines of 2 equations.
