Assume there are two linear equations:
a_1 x + b_1 y +c_1=0
a_2 x + b_2 y +c_2=0

The solution is x=\frac{b1*c2-c1*b2}{a1*b2-a2*b1}, y=\frac{a2*c1-a1*c2}{a1*b2-a2*b1}

You can drag the circle to change the slope of the linear equation or drag the square to change the offset of the linear equations.

There is a similar applet: Solving linear equations

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
