Consider the first inequality, we have
Consider the first inequality, we have
$\begin{array}{rcl}
x-\dfrac{x-1}{2} & > & 5 \\
\dfrac{2x-(x-1)}{2} & > & 5 \\
x + 1 & > & 10 \\
x & > & 9
\end{array}$
Consider the second inequality, we have
$\begin{array}{rcl}
1 & < & x - 11 \\
x & > & 12
\end{array}$
Therefore, the overall solution is $x > 9$.
