This is tricky because it has a lot of variables, but we just have to treat this problem normally.
separate y from p + n (feel free to check that you can do this by multiplying y out again and seeing that we have the same thing as before)
divide p + n on both sides

By using the principles of inverse variation, it is determined that it would take 20 workers 38 days to build a similar house.
The problem is an example of inverse variation, where the amount of time (days) to build a house decreases if the number of workers increases. In this specific scenario, one house was built in 76 days by 10 workers. We can represent the inverse variation relationship with the equation: days * workers = constant.
Using the given data, the constant can be calculated by multiplying the days by the number of workers, hence:
constant = 76 days * 10 workers = 760
To find the number of days it would take for 20 workers to build the house, we divide the constant by the number of workers:
days = constant / workers = 760 / 20 = 38 days
This means that it would take 20 workers 38 days to build a similar house.

The number 10 increased by 6 and then doubled equals 32.
To express the situation where a number (x) is increased by 6 and then the sum is doubled, we can write it as:
2(x + 6)
In this expression, (x + 6) represents the number increased by 6, and then multiplying the sum by 2 doubles the result.
For example, if the number x is 10, then the expression would be:
2(10 + 6) = 2(16) = 32
So, in this case, the number 10 increased by 6 and then doubled equals 32.
