The system is in equilibrium. The 6 kg mass is supported by two segments of the string, each providing a tension equal to $Mg/2$. The 3 kg mass is supported by a single string with tension $Mg/2$. Since $M_{1}g=6g$ and $2T=6g$, $T=3g$. For the 3 kg mass, $M_{2}g=3g$. Since $T=M_{2}g$, the 3 kg mass is also in equilibrium. Thus, the acceleration of the 6 kg mass is 6.66
