Tems11 [23]

Answer:

See explanation for answer.

Step-by-step explanation:

xy −3y(x−4z)

=xy + −3xy + 12yz

=xy + −3xy + 12yz

= (xy+−3xy) + (12yz)

=−2xy + 12yz

Answer:

= −2xy + 12yz

I'm sorry if this is incorrect.

I hope I helped!

Have a lovely day!

Side note:

I don't completely know what algebraic process is so I just solved it like I

would with a regular equation. If that's even what this is. If you have the

time then please tell me if I answered your question and if I didn't then

please tell me what I did wrong.
