Answer:


x=11

Explanation:

we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

so

In this problem


(x+5)=(1)/(2)(3x-1)

solve for x

Multiply by 2 both sides


2x+10=3x-1

subtract 2x both sides


10=3x-1-2x


10=x-1

Adds 1 both sides


x=11
