Answer 3

It looks like there's a mix of Russian and mathematical symbols in your question. I'll try to interpret and address the mathematical part of your question. It seems like you have an equation that needs to be solved. The equation is given as:

A) 2x + 3 - 40 = 0 B) 4x - 3 + 2x + 1 + ____ = ____ C) 5 + 2

Let's solve each part of this equation step by step.

Solving A) 2x + 3 - 40 = 0:

To solve for x, we can start by simplifying the equation:

2x + 3 - 40 = 0 2x - 37 = 0

Now, let's solve for x:

2x = 37 x = 37 / 2 x = 18.5

So, the solution for A) is x = 18.5.

Solving B) 4x - 3 + 2x + 1 + ____ = ____:

It seems like there are missing numbers in this part of the equation, represented by underscores. If you have specific numbers to fill in, please provide them so that I can help you solve this part of the equation.

Solving C) 5 + 2:

This part is a simple addition:

5 + 2 = 7

So, the solution for C) is 7.

If you have specific values to fill in for part B), please provide them so that I can help you solve the entire equation.
