Question

Правильно ли 5а-2(х-2) = 5а-2х-4

Answer 1

5а - 2(х-2) = 5а - 2х - 4

Раскрываем скобки:

5а - 2х + 4 = 5а - 2х - 4, а это неверно.

Ответ: неверно.

Удачи)

Answer 2

5а-2(х-2)=5а-2х-4
5а-2х+4=5а-2х-4
Ответ:нет неверно

Answer 3

Let's check if the equation is true by simplifying both sides:

Given equation: 5a - 2(x - 2) = 5a - 2x - 4

First, distribute the -2 on the left-hand side:

5a - 2 * x + 2 * 2 = 5a - 2x - 4

Now, simplify both sides:

5a - 2x + 4 = 5a - 2x - 4

At this point, we can see that the equation is not true. The left-hand side of the equation is 5a - 2x + 4, and the right-hand side is 5a - 2x - 4. The only difference is the constant term: +4 on the left and -4 on the right.

Thus, the correct equation should be: 5a - 2(x - 2) = 5a - 2x + 4
