Question

14-(5x-6,1/7)=6/7(5-12x)

Answer 1

Ответ:

-3

Пошаговое объяснение:

14 - 5x + 6 1/7 = 30/7 - 72x/7 |*7

98 - 35x + 43 = 30 - 72x

37x = -111

x = -3

Answer 2

Ответ:

x = -99/133

Пошаговое объяснение:

14 - 5x + 61/70 = 30/7 - 24x

(24 - 5)x= -1/70 - 14

19x = -1/70 - 14

x = (-1/70 - 14)/19

x = (-99/70)/19

x = -99/133

Answer 3

To solve the equation, let's simplify it step by step:

1. Distribute the factor on the left side: 14 - (5x - 6) * 1/7 = 6/7(5 - 12x)

2. Remove the parentheses on the left side: 14 - (5x/7 - 6/7) = 6/7(5 - 12x)

3. Distribute the factor on the right side: 14 - 5x/7 + 6/7 = 6/7 * 5 - 6/7 * 12x

4. Simplify both sides: 14 - 5x/7 + 6/7 = 30/7 - 72x/7

5. Move x terms to one side and constants to the other side: 14 + 6/7 - 30/7 = 5x/7 - 72x/7

6. Combine constants on the left side: (98 + 6 - 30) / 7 = (5x - 72x) / 7

7. Simplify: 74 / 7 = -67x / 7

8. Solve for x: x = (74/7) / (-67/7)

9. Simplify the right side: x = 74 / -67

Now, if you want to get the decimal value of x, you can divide 74 by -67:

x ≈ -1.10447761194 (approximately)
