Answer: PR = 22 / or 9x+4 in equation

Step-by-step explanation:

PR is given 14x-6

We can use PQ and QR equations since they equal PR

14x-6=3x+6x+4

14x-6=9x+4

add six to both sides

14x=9x+10

subtract 9x from both sides

5x=10

Divide by 5

x = 2

This step Isn't needed this is to check your answer.

14(2)-6

28-6 = 22

3(2) = 6

6(2)+4 = 16

6 + 16 = 22

It checks out :D
