Question

P+42–2p+9p=100-22 помогите хочу проверить дз

Answer 1

To solve the equation 42 - 2p + 9p = 100 - 22, we can simplify both sides of the equation and then solve for the variable p.

Let's break down the steps:

1. Simplify both sides of the equation: - On the left side, combine like terms: -2p + 9p = 7p. - On the right side, simplify: 100 - 22 = 78. - The equation becomes: 42 + 7p = 78.

2. Solve for p: - To isolate the variable p, we need to get rid of the constant term on the left side. We can do this by subtracting 42 from both sides of the equation: 42 + 7p - 42 = 78 - 42. - Simplifying further, we have: 7p = 36.

3. Finally, solve for p by dividing both sides of the equation by 7: - p = 36 / 7.

Therefore, the solution to the equation 42 - 2p + 9p = 100 - 22 is p = 36/7.

I hope this helps! Let me know if you have any further questions.
