Answer:

Add 4 positive unit tiles to each side

Explanation:

The tiles represent an algebraic equation. The first step in solving an equation like this is moving all constants to one side. The constants are the numbers with variables or x's. By adding 4 units to both sides all constants are on the right side. All the other choices would leave some constants on both sides.
