Emily's first step involves rewriting \(3(4x)\) as \((3 \cdot 4)x\). This transformation uses the associative property of multiplication, which states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product.
So the correct answer is:
associative property of multiplication.
