Answer 3

Let's use algebra to solve this problem. Let's denote the number of dresses as "d" and the number of suits as "s."

According to the information given:

1. The number of suits is 4 more than the number of dresses: s = d + 4
2. The number of pants is 10 less than the number of suits: p = s - 10

We know that they have sewn a total of 26 dresses and suits. So, the sum of dresses and suits is equal to 26: d + s = 26

Now we can substitute the value of "s" from the first equation into the second equation:

p = (d + 4) - 10 p = d - 6

We are looking for the value of "p" (pants), so we need to find the value of "d" (dresses) first.

Next, we'll use the sum of dresses and suits:

d + s = 26

Substitute the value of "s" from the first equation into the above equation:

d + (d + 4) = 26 2d + 4 = 26 2d = 26 - 4 2d = 22 d = 22 / 2 d = 11

So, they made 11 dresses (pлатьев) and now we can find the number of pants:

p = d - 6 p = 11 - 6 p = 5

Therefore, they sewed 5 pants (брюк) in the atelier.
