Answer: =−x−7y

Step-by-step explanation:

First, Distribute the Negative Sign:

=3x −2y+ −1(4x+5y),

=3x+ − 2y + − 1(4x) + −1 (5y),

=3x+ −2y + −4x + −5y

Then, Combine Like Terms:

=3x+−2y+−4x+−5y

=(3x+−4x)+(−2y+−5y)

Finally you get the answer :

= −x + −7y

* Hopefully this helps:) Mark me the brainliest:)!!

Answer:

-x - 7y

Step-by-step explanation:

First, get rid of the parentheses by multiplying them out. Multiply them by one for them to go away.

Now, you have 1(3x - 2y) - 1(4x + 5y).

Now simplify, and it's 3x - 2y - 4x - 5y (Yes, -5y! It's beause -1 * 5y = -5y. The sign is supposed to change).

Ok. The next is easy: Identify your matching variables.

3x , -4x and -2y , -5y

So, we're going to assume x comes before y in the new equation, as that's how it is alphabetically, and that's it.

-x - 7y.

Hope this helps!
