The correct first step in solving the equation 4(x – 3) = 9 is: Apply the distributive property to get 4x – 12 = 9.
Explanation:
The distributive property is used to eliminate the parentheses in the equation. By multiplying 4 by both terms inside the parentheses (x and -3), you get 4x – 12. This simplification is necessary before proceeding to isolate x.
