Answer 2

I can help you with your math problem.

Your question is: Answer in detail. Please help me solve it. Dear ones, please !!! The boy bought a notebooks for b hryvnias, 4 pens for x hryvnias, and he had 40 hryvnias left. How many hryvnias did the boy have at first?

To solve this problem, we need to write an equation that represents the situation. Let's use C to denote the amount of money that the boy had at first. Then we can write:

C - a * b - 4 * x = 40

This equation means that the boy spent a * b hryvnias on notebooks and 4 * x hryvnias on pens, and he had 40 hryvnias left after that. To find C, we need to isolate it on one side of the equation by adding a * b and 4 * x to both sides. We get:

C = a * b + 4 * x + 40

This is the answer. The boy had a * b + 4 * x + 40 hryvnias at first.
