(140-60)/2000 + 60/1000=0,04+0,06=0,1

Answer 2

To solve the equation (140-в)/2000 + в/1000 = 0.1, we can follow these steps:

1. Multiply the entire equation by 2000 to eliminate the denominators: - (140-в) + 2в = 200

2. Simplify the equation: - 140 - в + 2в = 200 - в + 140 = 200

3. Subtract 140 from both sides of the equation: - в = 200 - 140 - в = 60

Therefore, the value of в that satisfies the equation is 60.
