First, balance Br atoms. So on the RHS you get
Br2 + H2 O2  ====> 2 Br O2 + H2 O
Now  let n be num of molecules of H2O2.

Br2 +  n  H2 O2 ==>  2 Br O2  +  x  H2O
2n H atoms on left  and 2 x  H atoms on right    =>  n = x
now  2n atoms of O on LHS.    4 + n on right side.
=>  2n = 4 + n    =>  n = 4

Br2 +  4  H2 O2 ==>  2 Br O2  +  4  H2O
