OpenStudy (mathstudent55):
Is this the problem?

yes it is
OpenStudy (mathstudent55):
To divide, you multiply by the reciprocal:
\( =\dfrac{1}{x - 5} \times \dfrac{1}{5} \)
\( =\dfrac{1}{5(x - 5) } \)

ok i see how you did that
OpenStudy (anonymous):
so would my answer be 2-x/x
OpenStudy (anonymous):

can you help me @robtobey
OpenStudy (anonymous):
\[\frac{1}{5} \left(\frac{10}{x}-5\right)\text{=}\frac{2-x}{x}\]\[\left(\frac{1}{5}\right)\frac{10}{x-5}=\frac{2}{x-5} \]
