Concept:To make $n$ the subject, rearrange the equation so that $n$ is alone on one side.Solution:Start with the given relation:$y = \frac{n-x}{x}$Multiply both sides by $x$ to remove the denominator:$x \cdot y = n - x$Now add $x$ to both sides so that $n$ stands alone:$xy + x = n$Factor out the common factor $x$ from the left side:$x(y+1) = n$Therefore, rewriting with $n$ on the left gives:$n = x(y+1)$This matches option A.Answer:Option A ($n = x(y+1)$)
