Answer 2

У двух друзей вместе 16 солдатиков. Если один из них даст другому одного солдатика, то у них станет поровну. Сколько солдатиков у каждого?

Solution:

Let's assume that one friend has x soldiers and the other friend has y soldiers.

According to the given information, the total number of soldiers is 16. So we can write the equation:

x + y = 16 If one friend gives the other one soldier, then they will have an equal number of soldiers. This can be represented by the equation:

x - 1 = y + 1

Simplifying this equation, we get:

x - y = 2 Now we have a system of two equations:

x + y = 16 x - y = 2 To solve this system of equations, we can use the method of substitution or elimination.

Let's use the method of elimination to solve the system:

Adding the two equations together, we get:

(x + y) + (x - y) = 16 + 2

Simplifying, we have:

2x = 18

Dividing both sides by 2, we find:

x = 9

Substituting the value of x back into one of the original equations, we can solve for y:

9 + y = 16

Subtracting 9 from both sides, we get:

y = 7

Therefore, one friend has 9 soldiers and the other friend has 7 soldiers.

So, each friend has 9 soldiers and 7 soldiers respectively.
