4P + 3Q - 4R / P - R =

Question

What is the answer and how does one go about solving it?

Answer 1

It seems your equation is:

(4P + 3Q - 4R) / (P - R) = 19

(4P - 4R)  + 3Q = 19(P - R)

3Q = 15(P - R)

Q = 5(P - R)​

5S - Q = 0, where S = P - R

from (5S - Q = 0),

S = t
Q = 5t

from (S = P - R = t)

P = k + t

R = k

A final Solution is: P = k + t, Q = 5t, R = k, k,t > 1

To be fair, the question was resubmitted with a value after the equals. That will influence your solution.

I see it now, thanks.
