The inequality would start out looking like this:
[tex]-30\ \textless \ \frac{5}{9} (F-32)\ \textless \ 130[/tex]
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
[tex]-270\ \textless \ 5(F-32)\ \textless \ 1170[/tex]
Then distribute the 5 into the parenthesis:
[tex]-270\ \textless \ 5F-160\ \textless \ 1170[/tex]
Now add 160 everywhere:
[tex]-110\ \textless \ 5F\ \textless \ 1330[/tex]
and finally divide everything by 5:
-22<F<266
