зеленої більше на 8 => (х-3)+8=15

х=10

Problem Analysis

Let's break down the information provided in the question:

- Initially, 15 cans of green paint were purchased. - A certain number of cans of white paint were also purchased. - After using 3 cans of white paint, the number of green cans increased by 8.

We need to determine the number of cans of white paint that were purchased.

Solution

Let's assume the number of cans of white paint purchased is represented by the variable 'x'.

According to the information given, the following equation can be formed:

15 (initial cans of green paint) + x (cans of white paint) - 3 (used cans of white paint) = 15 (final cans of green paint) + 8 (additional cans of green paint)

Simplifying the equation:

15 + x - 3 = 15 + 8

x - 3 = 23

Adding 3 to both sides of the equation:

x = 26

Therefore, 26 cans of white paint were purchased.

Answer

The number of cans of white paint purchased is 26.
