Answer 1

Ответ:

а = 167

k = 50

y = 61

x = 99

y = 7.8

x = 7

x = 24

Пошаговое объяснение:

1. 566 - а = 399

а = 566 - 399

а = 167

2. k ÷ 25 = 2

k = 25 × 2

k = 50

3. 3721 ÷ y = 61

y = 3721 ÷61

y = 61

4. 23x - 27 = 2250

23x = 2250 + 27

23x = 2277

x = 2277÷23

x = 99

5. 510 - 9y= 438

9y= 510 - 439

9y= 71

y = 71 ÷9

y = 7.8

6. 8x + 7x = 105

15x = 105

x = 105 ÷ 15

x = 7

7. 37x - 21x + 8 = 200

37x - 21x = 200 - 8

37x - 21x = 192

8x = 192

x = 192 ÷ 8

x = 24

Answer 2

It seems like you have a system of equations that you'd like to solve for the variables a, b, k, y, and x. Let's break it down step by step:

1. 566 - a = 399 To solve for 'a,' subtract 399 from both sides of the equation: 566 - a - 399 = 399 - 399 167 - a = 0

   Now, add 'a' to both sides to isolate 'a': 167 - a + a = 0 + a 167 = a

   So, a = 167.

2. b - 608 = 199 To solve for 'b,' add 608 to both sides of the equation: b - 608 + 608 = 199 + 608 b = 807

   So, b = 807.

3. k:25 = 23721 To solve for 'k,' multiply both sides of the equation by 25: k/25 * 25 = 23721 * 25 k = 592,525

   So, k = 592,525.

4. 10 - 9y = 4388x + 7x Combine like terms on the right side: 10 - 9y = (4388 + 7)x 10 - 9y = 4395x

   Now, solve for 'x' by dividing both sides by 4395: (10 - 9y)/4395 = x

5. 8 = 200 This equation is not valid because 8 cannot equal 200. It appears to be an incorrect equation.

Let's leave the equation 'y = 6123x - 27 = 2250' as is because it's not clear what you're trying to solve for with this equation.
