A container is divided into two chambers by a partition. The volume of first chamber is $\displaystyle 4.5$ litre and second chamber is $\displaystyle 5.5$ litre. The first chamber contain $\displaystyle 3.0$ moles of gas at pressure $\displaystyle 2.0$ atm and second chamber contain $\displaystyle 4.0$ moles of gas at pressure $\displaystyle 3.0$ atm. After the partition is removed and the mixture attains equilibrium, then, the common equilibrium pressure existing in the mixture is $\displaystyle x \times 10^{-1} \mathrm{~atm}$. Value of $\displaystyle x$ is \_\_\_\_.
