I believe 21
2 doubled is 4
4 + 5 is 9
a quarter of 9 is 3
3+9 is 12
12 plus two is fourteen and half of fourteen is 7
7 plus 14 is 21.

Andy has X-Marbles.
Gave Bob (X/2 + 2),
Bal. = X - (X/2 + 2) = X/2 - 2.
Gave Alex 1/4(X/2 - 2) + 5 = X/8 + 9/2,
Bal.=(X/2 - 2) - (X/8 + 9/2)=3X/8-13/2.
Gave Emily 1/2(3X/8 - 13/2) =
3X/16 -13/4.
Bal. = 3X/16 - 13/4.
3X/16 - 13/4 = 2,
Multiply both sides by 16:
3X - 52 = 32,
3X = 32 + 52,
3X = 84,
X = 84 / 3 = 28 Marbles.
Gave Bob (X/2 + 2),
Bal. = X - (X/2 + 2) = X/2 - 2.
Gave Alex 1/4(X/2 - 2) + 5 = X/8 + 9/2,
Bal.=(X/2 - 2) - (X/8 + 9/2)=3X/8-13/2.
Gave Emily 1/2(3X/8 - 13/2) =
3X/16 -13/4.
Bal. = 3X/16 - 13/4.
3X/16 - 13/4 = 2,
Multiply both sides by 16:
3X - 52 = 32,
3X = 32 + 52,
3X = 84,
X = 84 / 3 = 28 Marbles.

I Think it is 21 Because:
2 doubled is 4
4 + 5 is 9
a quarter of 9 is 3
3+9 is 12
12 plus two is 14 and 1/2 of 14 is 7
7 + 14 is 21.
so 21 is the answer
2 doubled is 4
4 + 5 is 9
a quarter of 9 is 3
3+9 is 12
12 plus two is 14 and 1/2 of 14 is 7
7 + 14 is 21.
so 21 is the answer
