Answer to -5x-6x<8-8n-n

EastWind [94]

First...
$Simplify\;-5x-6x \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-5x-6x=-11x$

$Simplify\;8-8n-n \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-8n-n=-9n$
$8 - 9n$

$-11x\ \textless \ 8-9n$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)} \ \textgreater \ 11x\ \textgreater \ -8+9n$

$\mathrm{Divide\:both\:sides\:by\:}11 \ \textgreater \ \frac{11x}{11}\ \textgreater \ -\frac{8}{11}+\frac{9n}{11}$

$Simplify \ \textgreater \ x\ \textgreater \ \frac{-8+9n}{11}$

Hope this helps!
