Answer:

Given the equation:
4(x-3) =9 ....[1]

The distributive property says that:


a \cdot (b+c) = a\cdot b+ a\cdot c

Apply the distributive property in [1] we get;


4 \cdot x - 4\cdot 3 = 9

Simplify:


4x - 12= 9

Therefore, the sentence that explains the correct first step i.,e
4x - 12= 9 for the given equation: Distributive property.
