let x=number of stamps Huili had at first.
x+120=number of stamps Nadiah had at first.
20%(x+120)=number of stamps Nadiah gave to Huili.
50%x=number of stamps Huili gave to Nadiah.
...
.50x+(x+120)-.20(x+120)+x=264
.50x+x+120-.20x-24-x=264
.30x=168
x=560
x+120=680
number of stamps Nadiah had at first=680
