Х=-1

Answer 2

Ответ:

Пошаговое объяснение:

0,4х + 5,4 = 2,8 - 2,2х

2,6х = -2,6

х = -1

Answer 3

To solve the given equation, let's simplify the expression and gather the variable terms on one side and the constant terms on the other side.

0.4x + 5.4 = 2.8 - 2.2x

First, let's combine like terms by adding 2.2x to both sides:

0.4x + 2.2x + 5.4 = 2.8 - 2.2x + 2.2x

This simplifies to:

2.6x + 5.4 = 2.8

Next, let's isolate the variable term by subtracting 5.4 from both sides:

2.6x + 5.4 - 5.4 = 2.8 - 5.4

This simplifies to:

2.6x = -2.6

Finally, divide both sides by 2.6 to solve for x:

(2.6x)/2.6 = (-2.6)/2.6

This simplifies to:

x = -1

Therefore, the solution to the equation is x = -1.
