Due to editing problems let me tell what the FBDs are :-

Mass 3kg - 3g down, N up , 120 left and T1 right

MASS 5kg :- 5g down N up, T1 left and T2 right.

Mass 7kg :- 7g down N up and T2 left.

Using these FBD we can derive three equations as seen in the pic. Solving these we will get a which is 8 m/s2 which if substituted in above equations would provide us with T1 and T2
