Question

арбуз+дыня+тыква=20,арбуз+тыква+кабачок=17,дыня+кабачок+тыква=14,арбуз+дыня+кабачок=15 сколько весит каждый овощ

Answer 1

Дано:

А+Д+Т=20

А+Т+К=17

Д+К+Т=14

А+Д+К=15

Решение:

3А+3Д+3Т+3К=66

А+Д+Т+К=22

А+Д+Т-(А+Д+К)=5 => Т-К=5

А+Т+К-(Д+К+Т)=3 => А-Д=3

А+Д+Т+К-(А-Д)-(Т-К)=22-3-5 => Д+К=7

А+Д+Т+К-(Д+К)=22-7 => А+Т=15

Подставим в исходные

7+Т=14 => Т=7

15+Д=20 => Д=5

А+7+5=20 => А=8

8+5+К=15 => К=2

Answer 2

To solve this problem, we can assign variables to the weights of each fruit/vegetable. Let's use the following variables:

Let's use the following variables:

• Weight of arbuз: A
• Weight of дыня (watermelon): B
• Weight of тыква (pumpkin): C
• Weight of кабачок (zucchini): D

Now, we have the following equations based on the given information:

1. A + B + C = 20
2. A + C + D = 17
3. B + D + C = 14
4. A + B + D = 15

Now we can solve this system of equations to find the values of A, B, C, and D. Let's do that:

Step 1: Subtract equation 3 from equation 1 to eliminate B: (A + B + C) - (B + D + C) = 20 - 14 A - D = 6 ...........(5)

Step 2: Subtract equation 4 from equation 2 to eliminate B: (A + C + D) - (A + B + D) = 17 - 15 C - B = 2 ...........(6)

Step 3: Add equation 5 and equation 6 to eliminate B and D: (A - D) + (C - B) = 6 + 2 A + C - (B + D) = 8

Now we can substitute the values from equation 4 (A + B + D = 15): A + C - 15 = 8 A + C = 23 ...........(7)

Step 4: Add equation 3 to equation 5 to find the value of C: (B + D + C) + (A - D) = 14 + 6 B + A = 20 ...........(8)

Now we can use equation 7 (A + C = 23) to find the value of B: B = 23 - A ...........(9)

Step 5: Substitute the value of B from equation 9 into equation 8: (23 - A) + A = 20 23 = 20 (This indicates there might be an error in the given equations, as this equation is not true)

It seems there's an inconsistency in the given information. The system of equations provided doesn't have a consistent solution based on the information provided. Please double-check the equations or provide additional information to resolve the issue and find the weights of each fruit/vegetable accurately.
