Hey there, hope i can help!
[tex]\mathrm{Add\:}99\mathrm{\:to\:both\:sides} \ \textgreater \ 11x-99+99=201-x+99[/tex]
Simplify
[tex]11x=-x+300[/tex]
[tex]\mathrm{Add\:}x\mathrm{\:to\:both\:sides} \ \textgreater \ 11x+x=-x+300+x[/tex]
Simplify again
12x = 300
[tex]\mathrm{Divide\:both\:sides\:by\:}12 \ \textgreater \ \frac{12x}{12}=\frac{300}{12}[/tex]
Simplify once more
x = 25
Hope this helps!
