Answer 1

Ответ:

-8,5(х+2у)+1,7(5х-4у)-х-11у=  -8,5х-17у+8,5х-6,8у-х-11у=  х-34,8у

Пошаговое объяснение:

Answer 2

To simplify the expression:

-8.5(x + 2y) + 1.7(5x - 4y) - x - 11y

First, distribute the coefficients:

-8.5x - 17y + 1.7 * 5x - 1.7 * 4y - x - 11y

Now, perform the multiplications:

-8.5x - 17y + 8.5x - 6.8y - x - 11y

Now, combine like terms:

(-8.5x + 8.5x - x) + (-17y - 6.8y - 11y)

The x-terms cancel each other out, and you can add the y-terms:

0x - 34.8y

Since 0x is just 0, the final simplified expression is:

-34.8y
