Make \(\frac{a}{x}\) the subject of formula \(\frac{x + a}{x - a}\) = m
\(\frac{m - 1}{m + 1}\)
\(\frac{m + 1}{1 - m}\)
\(\frac{1 - m}{1 + m}\)
\(\frac{m + 1}{m - 1}\)

The numerator was solved as (x+a) in the solution but written as (x+1) in the question which makes it difficult to get the answer
The question is wrongly composed. It is supposed to be x+a/x-a=m not x+1/X-a=m . It is even stated in the solution. kindly make due and necessary corrections.
The question is wrongly composed:
nothing is given as to get the subject of the formula
REF: check the question
There is no “=m” in the question. Although I suppose I should have guessed since there was an “m” in every answer
(x + a)/(x - a) = m
mx - ma = x + a
mx - x = ma + a
x(m - 1) = a(m + 1)
a/x = (m + 1)/(m - 1)
