x = 4
Step-by-step explanation:
expand out the brackets to get 7 - 2x = 2x - 8 - 1
we can then add 2x to both sides to get 7 = 4x - 8 - 1
add 9 to both sides to get 16 = 4x
divide both sides by 4 to get x = 4

We have six ladies and name them:
1,2,3,4,5,6
where 5 and 6 are the daughters of 3 and 4, 3 and 4 are daughters of 1 and 2.
Now,
1 and 2 are mothers of 3 and 4 = 2 mothers
3 and 4 are mothers of 5 and 6 = 2 mothers
1 and 2 are the grandmothers of 5 and 6 = 2 grandmothers
5 and 6 are the daughters of 3 and 4 = 2 daughters
3 and 4 are the daughters of 1 and 2 = 2 daughters
2 granddaughters 5 and 6
So now you have a list of 12 people ! ... 4 mothers, 2 grandmothers,
4 daughters, and 2 grand-daughters ... and they all get in to the Christmas Market with only six tickets.
