I think there is a problem in what was asked; I do not think that you are intended to be able to determine x.

Explanation:

Here is what I think the question was intended to be:
QUESTION:
Given
color(white)("XXX")m/_RPS=8x+7
and
color(white)("XXX")m/_QPR=9x+16
Find /_QPcolor(red)S
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SOLUTION:
/_QPS
color(white)("XXX")=color(white)("xxxx")8x+color(white)("x")7
color(white)("XXxxxX")ul(+color(white)("x")color(white)("x")9x+16)
color(white)("XXX")=color(white)("xxx")17x+23

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is no way with the given information for you to find the value of x, so you can not improve upon what you are directly given for m/_QPR (namely =9x+16)
