Answer:

The value of x is 6

Explanation:

* Lets explain how to solve the problem

- Point Q is the mid-point of the segment PR

Q is the mid-point of segment PR

∴ Q divided the segment PR into two equal parts

- When point Q divided the segment PR into two equal parts,

then the two parts are PQ and QR

PQ = QR

∵ PQ and QR are 7x - 16 and 4x + 2

7x - 16 = 4x + 2

- Subtract 4x from both sides

∴ 7x - 4x - 16 = 2

∴ 3x - 16 = 2

- Add 16 to both sides

∴ 3x = 2 + 16

∴ 3x = 18

- Divide both sides by 3

∴ x = 6

The value of x is 6
