Let's solve your equation step-by-step.
5/7x−1/3x=8
Step 1: Simplify both sides of the equation.
5/7x 1/3x=8
5/7x+ −1/3x=8
(5/7x+ −1/3x)=8(Combine Like Terms)
8/21 x=8
8/21x=8
Step 2: Multiply both sides by 21/8.
(21/8)*(8/21x)=(21/8)*(8)
Answer:
x=21
The equation of Q(n) is 
<h3>How to determine the formula of Q(n)?</h3>
The functions are given as:


From the question, we understand that:
d = P(n)
This means that:
d = 88n + 23
Substitute d = 88n + 23 in R(d)

Also, from the question
Q(n) = R(n)
So, we have:

Hence, the equation of Q(n) is
