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
