Манижа собрала букет, в котором алых и белых роз 5, белых и оранжевых роз 4, оранжевых и алых роз 7. Сколько белых роз в букете?

Answer 1

Х       у                у      z                z      x
ал.   бе.            бе.  ор.              ор.  ал.
---------              ----------              ----------
    5                       4                        7

x + y =5          y=5-x
y + z = 4    →  z=4-y 
z + x = 7         x=7-z              
 
           y= 5-x
            y=5-( 7-z ) 
           y=5-( 7-(4-y))
          y=5-(7-4+y)
           y=5-7+4-y
           y=5-3-y
           2y=2
            y=1       ответ -1

Answer 3

Calculation of White Roses in the Bouquet

To determine the number of white roses in the bouquet, we need to analyze the information provided. According to the given information, the bouquet consists of three combinations of roses:

1. Red and White Roses: There are 5 red and white roses in the bouquet. 2. White and Orange Roses: There are 4 white and orange roses in the bouquet. 3. Orange and Red Roses: There are 7 orange and red roses in the bouquet.

We need to find the number of white roses in the bouquet. Unfortunately, the given information does not directly provide the number of white roses. However, we can use a system of equations to solve for the number of white roses.

Let's assume that the number of white roses in the bouquet is represented by the variable 'x'. Using this assumption, we can set up the following equations:

1. Red and White Roses: x + 5 = ? 2. White and Orange Roses: 4 + x = ? 3. Orange and Red Roses: 7 + x = ?

Unfortunately, the given information does not provide the missing values in the equations. Therefore, it is not possible to determine the exact number of white roses in the bouquet based on the information provided.
