Answer 1

x+2x=30

3x=30

x=10

2x=20

по другому не знаю как только вот так

Answer 2

Solution:

Let's solve this problem using a system of equations. Let's assume the number of pencils in the first box is represented by x and the number of pencils in the second box is represented by y.

We are given two pieces of information: 1. There are 30 pencils in total. 2. The number of pencils in one box is twice the number of pencils in the other box.

We can represent this information in the form of equations: 1. x + y = 30 (Total number of pencils is 30) 2. x = 2y (The number of pencils in one box is twice the number in the other)

Now, we can solve these equations to find the values of x and y.

Calculation:

Using the second equation, we can express x in terms of y: x = 2y

Substitute this value of x into the first equation: 2y + y = 30 3y = 30 y = 10

Now that we have the value of y, we can find the value of x using the equation x = 2y: x = 2 * 10 x = 20

Answer:

So, there are 20 pencils in one box and 10 pencils in the other box.
