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

Has the right answer so that is that. The cat is 20 taller than the turtle, but their absolute heights are undefined.

$\left \{ \begin{matrix} x+c & = & t+170 \\ x+t & = & c+130 \end{matrix} \right. \\ \left \{ \begin{matrix} x-t & = & -c+170 \\ x+t & = & c+130 \end{matrix} \right. \\ 2x=300 \\ x=150$
