Maggie brought 3 sandwiches to the picnic .
In the question ,
it is given that
Maggie bought oranges and sandwiches to a picnic .
given the number of oranges = 9
also given that , number of oranges was three more than twice the number of sandwiches
let the number of sandwiches Maggie brought to a picnic be x .
So , the number of oranges is = 2x + 3
So , 2x + 3 = 9
Subtracting 3 from both the sides ,
we get ,
2x = 9 - 3
2x = 6
On dividing both sides by 2,
we get ,
x = 6/2
x = 3
Therefore , the number of sandwiches = 3 .
