Show that point M is a midpoint on a line | Geometry

The video tutorial explains how to determine if a point is the midpoint of a line segment. It begins by introducing the problem and the concept of a midpoint. The teacher defines the midpoint as a point that divides a line segment into two equal parts. The tutorial then demonstrates solving for the variable X using algebraic expressions and verifies the midpoint by calculating and comparing segment lengths. The conclusion confirms the point as the midpoint by showing equal lengths on both sides.

What value of X did we find, and how does it help in proving M is the midpoint?

After calculating the lengths of AM and MB, what conclusion can we draw about point M?
