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
