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#)
