Answer:

-10y

Step-by-step explanation:

=5x-5y-5y-5x

=5x-5x-5y-5y

=-10y

[tex]\huge\boxed{\mathrm{\underline{\boxed{Hi\:there, \:hope\:you\:are\:having\:a\:great\:day.}}}}[/tex]5(x-y)-5(y+x)

Let's use the Distributive Property to help us solve.

5(x-y)-5(y+x)

5x-5y-5y-5x

Now, all we have to do is combine like terms.

=>5x-5x-5y-5y

=>-10y
