Answer 2

Problem Analysis

We are given the following information: - Masha made 45 yellow toys. - She made the same number of red and blue toys. - The number of blue toys is twice as less as the number of yellow and red toys combined.

We need to find the number of red toys Masha made.

Solution

Let's assume the number of red toys Masha made is x.

According to the given information: - The number of yellow toys = 45 - The number of red toys = x - The number of blue toys = x

The number of blue toys is twice as less as the number of yellow and red toys combined. This can be expressed as:

2 * (x + 45) = x

Simplifying the equation:

2x + 90 = x

Subtracting x from both sides:

x + 90 = 0

Subtracting 90 from both sides:

x = -90

Since the number of toys cannot be negative, it means there is no valid solution for the number of red toys Masha made.

Therefore, there were no red toys made by Masha.

Answer

Masha did not make any red toys.
