Answer:
Helena has
marbles in all.
Explanation:
Let the total number of marbles be denoted by 'm'.
Helena found them and put them in 4 bags with m marbles in each bag.
Total marbles in 4 bags become =

Now, she had 3 marbles left over that didn't fit in the bags.
That gives total marbles as =

We can solve this using an example.
Suppose Helena had 15 marbles in total.
She divides these in 4 bags,
plus 3 extra.
Now, m = 3
So, putting the value of m as 3 in equation we get,

=

= 15
Therefore, we can say that Helena has
marbles in all.
