Answer 1

Ответ:

Пошаговое объяснение:

3-6+21х-18-24х=4

21х-24х=4+18+6-3

-3х=25

Х=25:(-3)

Х=-8 1/3

Answer 2

Ответ:

3-6+21х-18-24х=4

21х-24х=4-3+6+18

-3х=25

х=25:(-3)

х=8,3

Answer 3

To solve the equation, we need to simplify and then isolate the variable 'x' on one side of the equation. Let's start step-by-step:

1. Distribute the numbers outside the parentheses: 3 - 3(2 - 7x) - 6(3 + 4x) = 4

2. Perform operations inside the parentheses: 3 - 3(2) + 3(7x) - 6(3) - 6(4x) = 4

3. Simplify further: 3 - 6 + 21x - 18 - 24x = 4

4. Combine like terms: (21x - 24x) + (3 - 6 - 18) = 4

5. Combine x terms and constant terms: -3x - 21 = 4

6. Move constant terms to the right side of the equation: -3x = 4 + 21

7. Add the constants: -3x = 25

8. Finally, isolate x by dividing both sides by -3: x = 25 / -3

Now, let's calculate the value of 'x': x = -25/3

So, the solution to the equation is x = -25/3.
