The straight segment connecting midpoints of the two sides of a triangle is of half of the length of the third side of the triangle.
See the lesson The line segment joining the midpoints of two sides of a triangle in this site.
Therefore, solve the equation
5x - 6 = 24,
and you will have the answer: x = 6 units.
