Step-by-step explanation:
hey buddy...
thanks for question...
let no of men and women be x and y respectively
according to given conditions..(1)
4x+6y=9...(1)
according to given conditions..(2)
6x+3y=9...(2)
equation (2)×2--> 12x+6y=18....(3)
solve (1)&(3)
subtract (1)&(3)
12x+6y=18
4x+6y=9
- - -
___________
8x=9
x=8/9
substitute x=8/9 in (1)
4x+6y=9
4×8/9+6y=9
32+6y=81
6y=81-32
6y=49
y=49/6
to find 2x+2y=?
2×8/9+2×49/6
16/9+2×49/6
3.77×8.16
30.76
hope it helps mark me as brainliest
