Answer is D) take 5 blocks away from the left side.
There are 8 blocks on the left and only 3 on the right, 8 - 3 = 5
Since there are 8 block on the left side and 3 on the right side, they have to have the same amount to be equal.
A) 8 = 3 + 3 → 8 = 6? No, this isn't right
B) 8 = 4 + 3 → 8 = 7? Nope
C) 8 - 3 = 3 → 5 = 3? No
D) 8 - 5 = 5 → 3 = 3? Yes, so to balance the two sides you would need to take 5 blocks from the left side (or add 5 to the right side but that isn't a choice)
