Question

2+2х=5+3(х+2) решит уравнения

Answer 1

Ответ:

-9.

Объяснение:

2+2х=5+3(х+2)

2+2х=5+3х+6

2 - 5 - 6 = 3х - 2х

-9 = х

х = -9.

Проверка:

2+2•(-9) = 5 + 3(-9 + 2)

-16 = 5 - 21

-16 = -16 - верно.

Answer 2

Ответ:-9

Объяснение:2+2х=5+3(х+2)

2+2х=5+3х+6

2х-3х=5+6-2

-х=9

х=-9

Answer 3

To solve the equation 2 + 2x = 5 + 3(x + 2), we'll follow these steps:

1. Distribute the 3 to the terms inside the parentheses: 2 + 2x = 5 + 3x + 6

Simplifying further: 2 + 2x = 11 + 3x

2. Move all the x terms to one side of the equation and the constant terms to the other side. We can do this by subtracting 2x from both sides: 2 + 2x - 2x = 11 + 3x - 2x

Simplifying further: 2 = 11 + x

3. Move the constant term to the other side of the equation by subtracting 11 from both sides: 2 - 11 = 11 + x - 11

Simplifying further: -9 = x

Therefore, the solution to the equation 2 + 2x = 5 + 3(x + 2) is x = -9.
