i tried x=44 and i still don’t understand even with the lesson, what does x equal?

Answer:
x = 22
Step-by-step explanation:
B and F are midpoints of the triangle ACE
According to the triangle midpoint theorem, the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
So BF ║ CE and BF = 1/2 CE
Given: BF = 2x and CE = 88
Plug in BF = 1/2 CE
2x = 1/2 (88)
2x = 44
x = 22
