This is a system of linear equations in two unknowns computer
It can automatically merge similar items and calculate the answer!
In the process or show the simplified equation and calculation process๏ผ Android download
Update new version!
V3
Add no solution, infinitely many solutions, and infinitely many sets of solutions, and solve the problem that the formula โ of the binary linear simultaneous equation is not the unary linear equation (x) ! Android download link in the first post
linear equations are for grade 7-1 course, and 2 linear equations and plane coordinates are for grade 7-2
I hope to use it without affecting education๏ผ
