Answer:

The value of x is \frac{25}{2}.

Step-by-step explanation:

From Analytical Geometry we get that ratio of BC to BE is:

\frac{BC}{BE} = 2 (From definition of midpoint)

\frac{BE+CE}{BE} = 2

1 + \frac{CE}{BE} = 2

\frac{CE}{BE} = 1

CE = BE

If we know that BE = 50 and CE = 2\cdot x + 25, then, the equality above is expanded:

2\cdot x +25 = 50

2\cdot x = 25

x = \frac{25}{2}

The value of x is \frac{25}{2}.
