В

Пошаговое объяснение:

-0,1х+0,7х=-1,9-1,1

0,6х=-3

х=-5

Answer 2

To solve for x in the equation 1.1 - 0.1x = -1.9 - 0.7x, you can follow these steps:

1. First, let's simplify the equation by combining like terms. Add 0.7x to both sides of the equation to move the x terms to one side:

1.1 - 0.1x + 0.7x = -1.9 - 0.7x + 0.7x

This simplifies to:

1.1 + 0.6x = -1.9

2. Now, subtract 1.1 from both sides to isolate the term with x on the left side:

1.1 + 0.6x - 1.1 = -1.9 - 1.1

This simplifies to:

0.6x = -3.0

3. Finally, divide both sides by 0.6 to solve for x:

(0.6x) / 0.6 = (-3.0) / 0.6

x = -5

So, the solution to the equation is x = -5, which corresponds to option В) -5.
