Hello there! :) :D

Answer:

[tex]-\frac{3}{b}[/tex]

*The answer must have a fraction.*

Step-by-step explanation:

Lesson: Using properties to simplify expression.

Distributive property: a(b+c)=ab+ac

First, you had to factor by equation.

[tex]3a-36=3(a-12)[/tex]

[tex]\frac{3(a-12)}{12b-ab}[/tex]

Then, you factor out by the common term of b.

[tex]\frac{3(a-12)}{b(-a+12)}[/tex]

You can also cancel by the common factor of a-12.

[tex]\frac{3(a-12)}{b(-a+12)}=-\frac{3}{b}[/tex]

Hope this helps!

Thanks!

-Charlie

Have a great day!

:)
