Answer 1

Ответ:

Пошаговое объяснение:

= -4х + 2у + 6 - 4х + 2у = -8х + 4у + 6 =

2 * (-4х + 2у + 3)

Answer 2

To simplify the expression (2x - y - 3) * (-2) - 2 * (2x - y), you can distribute the constants and simplify further:

First, distribute -2 to each term inside the first parentheses:

-2 * (2x - y - 3) = -2 * 2x + (-2) * (-y) + (-2) * (-3) = -4x + 2y + 6

Now, distribute -2 to each term inside the second parentheses:

-2 * (2x - y) = -2 * 2x + (-2) * (-y) = -4x + 2y

So the expression becomes:

(-4x + 2y + 6) - (-4x + 2y)

Now, you can simplify further by removing the parentheses:

-4x + 2y + 6 + 4x - 2y

Now, notice that the terms -4x and 4x cancel each other out, and the terms 2y and -2y also cancel each other out:

-4x + 4x + 2y - 2y + 6

The terms with x and y have canceled each other out, leaving only the constant term 6:

6

So, the simplified expression is just 6.
