cat+table−turtle=170     (i)  turtle+table−cat=130     (ii)  (i)+(ii)  2table=300 ⇒ table=150
$$\mathrm{cat}+\mathrm{table}−\mathrm{turtle}=\mathrm{170}\:\:\:\:\:\left(\mathrm{i}\right) \\ $$$$\mathrm{turtle}+\mathrm{table}−\mathrm{cat}=\mathrm{130}\:\:\:\:\:\left(\mathrm{ii}\right) \\ $$$$\left(\mathrm{i}\right)+\left(\mathrm{ii}\right) \\ $$$$\mathrm{2table}=\mathrm{300}\:\Rightarrow\:\mathrm{table}=\mathrm{150} \\ $$
