You can use ICE table to solve this problem
        2 NH3 -----> N2  + 3H2
     I    76 cm          0       0
     C  -2x                x       3x

after decomposition  a change of 6cm of Hg was observed
so sum of all changes should be equal to 6 cm of Hg
means  -2x + x + 3x = 6cm
get the value of x and then partial pressure of H2 which is 3x .
