x = table height, t = turtle height, c = cat height
left: x-t+c =170
right: x+t-c = 130
add them together, t and c cancel out:
2x = 300
x =150

\left \{
\begin{matrix}
x+c & = & t+170 \\
x+t & = & c+130
\end{matrix} \right.

\left \{
\begin{matrix}
x-t & = & -c+170 \\
x+t & = & c+130
\end{matrix} \right.

2x=300 \\
x=150
