Answer:

The solution included both distributive property and combined like terms.

Step-by-step explanation:

Given the equation;


\begin{gathered} 9(a-3)-4 \\ 9(a)-9(3)-4 \\ 9a-27-4 \\ 9a+(-27-4) \\ 9a-32 \end{gathered}

On the second step we can notice that we have applied the distributive property of multiplication over addition. which states;


a*(b+c)=a* b+a* c

which is similar to;


9(a-3)=9(a)-9(3)

Also, on the fourth step, the like terms were combined.


9a+(-27-4)

Therefore, the solution included both distributive property and combined like terms.
