; This is a simple example of eliminate command usage. ; Combine the equations for 2 circles on a 2D Cartesian plane ; to find the points of intersection (x, y). (x-x1)^2+(y-y1)^2=r1^2 ; circle of radius r1 with center at (x1, y1) (x-x2)^2+(y-y2)^2=r2^2 ; circle of radius r2 with center at (x2, y2) eliminate x ; combine the two equations, removing the x variable from the result y ; solve for y simplify simplify
