Let the no. of males be 5a. the no. of women be 2a. there are 450 more males in the party.

=> 2a+450=5a

 5a-2a=450

a=450/3 =150.

no of females is 2a=2x150 =300

Let the numbers of males be 5 x
and the females be 2 x
but there are 450 more males than the females
we can write th eequation as
5x=2x+450
adding -2 x on both sides
3x=450
dividing both sides by 3
x=150
hence the number of females is
2x=2*150
=300
and the males is 5x
5x=5*150
=750
