Answer: The expression 6xy - 3xy can be simplified to 36 if x = 3 and y = 4.
Explanation:
First let's simplify the problem.
6xy - 3xy = 3xy
3xy
Now let's substitute x for 3 and y for 4.
3 x 3 x 4
Finally, let's solve using the associative property!
(3 x 3) x 4
= 9 x 4
= 36
3 x (3 x 4)
= 3 x 12
= 36
The expression 6xy - 3xy can be simplified to 36.
