Answer: B

Step-by-step explanation:

Given that DE is the mid point. Since DE is the midpoint, it will be equal to the half value of BC. That is,

DE = 1/2 × BC

Where

DE = 3x - 5

BC = 26

Substitute the values into the equation

3x - 5 = 1/2 × 26

3x - 5 = 13

Collect the like terms

3x = 13 + 5

3x = 18

x = 18/3

X = 6

The correct option is B
