Determine the endpoint given one endpoint and midpoint algebraically

The video tutorial explains how to find the other endpoint of a line segment when given one endpoint and the midpoint. It begins by introducing the points and the task, followed by an explanation of the midpoint concept. The midpoint formula is introduced, and equations are set up to solve for the unknown endpoint. The tutorial concludes with solving these equations to find the coordinates of the other endpoint.

Explain the process of solving for X1 and Y1 given the midpoint and one endpoint.
