Can someone help me? I'm lost.

First step is to find R
use The equation QR =43

R=43/Q
now since we have R plug that into PR= 9x - 31

P(43\Q) = 9x - 31
P43/QP +31 =9x
9x=P43÷QP +31
x=P43÷QP+31 /9

Since the question doesnt specify to leave the question in terms of P or Q i suppose this is the final answer

Hope this helps! xD
would not mind if you put it as the brainliest answer
