Answer 2

To simplify the expression -3×(2х-5у)-(5х-9у)-(2у-4х), we can distribute the negative sign and perform the necessary operations. Let's break it down step by step:

-3×(2х-5у) = -3×2х + 3×5у = -6х + 15у

-(5х-9у) = -5х + 9у

-(2у-4х) = -2у + 4х

Now we can combine the simplified terms:

-6х + 15у - (5х - 9у) - (2у - 4х)

Re-arranging the terms:

-6х - 5х + 4х + 15у + 9у - 2у

Combining like terms:

(-6х - 5х + 4х) + (15у + 9у - 2у)

-7х + 22у

Therefore, the simplified expression is -7х + 22у.
