Answer 3

It seems like you have provided an equation with some Cyrillic characters and symbols. To solve the equation, let's first rewrite it in a more standard mathematical notation:

3.5 - x = 8(x + 2.8)

Now, let's solve for the variable x:

1. Distribute the 8 on the right side of the equation:

3.5 - x = 8x + 8 * 2.8

2. Simplify the equation:

3.5 - x = 8x + 22.4

3. To isolate x on one side of the equation, you can start by moving the x terms to the left side and the constant terms to the right side:

3.5 - 22.4 = 8x + x

4. Simplify both sides:

-18.9 = 9x

5. Finally, solve for x by dividing both sides by 9:

x = -18.9 / 9 x ≈ -2.1

So, the solution to the equation is approximately x ≈ -2.1.
