If anything is unclear about what I did. You can ask for more info,..
To find n we have:
2n+2n+2n+10−n+19−n+29−n+n=90
4n=32
n=8
Now to find the total number of people that play football, we have:
F=2n+10−n+19−n+n=29+n=37
To find n we have:
2n+2n+2n+10−n+19−n+29−n+n=90
4n=32
n=8
Now to find the total number of people that play football, we have:
F=2n+10−n+19−n+n=29+n=37
Please how did you get 32
