Question

Please help whats the best way to solve this
4-s/9-s = 5/s-9

Answer 1

is this
\[\frac{4-s}{9-x}=\frac{5}{x-9}\]?

Answer 2

if so start with
\[\frac{s-4}{s-9}=\frac{5}{s-9}\] so
\[s-4=5\]
\[s=9\] but s cannot be 9 because that will make the denominator = 0 so there is no solution

Answer 3

in other words it is not possible that
\[\frac{4-s}{9-s}=\frac{5}{s-9}\]
