Answer 1

Ответ:

1) х=1

2) y=9

3) х1 = 1

х2 = -1/3

Пошаговое объяснение:

1) 7х+4,8-10х=1,8

-3х+4,8=1,8

-3х=1,8-4,8

-3х=-3

2) 17y+14y-145=134

17y+14y=134+145

31y=279

y=279:31

3) 17 - 4 |3х - 1 | = 9

|3х - 1 | = 2

Answer 2

To solve the equation 1 + 2(2,4 - 5x) + 7x = 1,8 + 2 + 17 + у + 314у = 14 + 3 + 17 - 4│3x - 1│ = 9, we need to simplify and isolate the variable x.

Let's break down the equation step by step:

1. Simplify the equation: - 1 + 2(2.4 - 5x) + 7x = 1.8 + 2 + 17 + у + 314у = 14 + 3 + 17 - 4│3x - 1│ = 9

2. Distribute the 2 to the terms inside the parentheses: - 1 + 4.8 - 10x + 7x = 1.8 + 2 + 17 + у + 314у = 14 + 3 + 17 - 4│3x - 1│ = 9

3. Combine like terms: - 5.8 - 3x + 7x = 20.8 + у + 314у = 34 - 4│3x - 1│ = 9

4. Simplify further: - 5.8 + 4x = 20.8 + у + 314у = 34 - 4│3x - 1│ = 9

5. Combine like terms: - 4x + 5.8 = 20.8 + у + 314у = 34 - 4│3x - 1│ = 9

6. Move the constant terms to the other side of the equation: - 4x = 20.8 + у + 314у - 5.8 = 34 - 4│3x - 1│ - 9

7. Simplify further: - 4x = 15 + у + 314у = 25 - 4│3x - 1│

8. Solve for x: - To solve for x, we need to isolate it on one side of the equation. Let's start by getting rid of the absolute value.

- Case 1: 3x - 1 ≥ 0 - In this case, the absolute value can be removed, so we have: - 4x = 15 + у + 314у = 25 - 4(3x - 1)

- Case 2: 3x - 1 < 0 - In this case, the absolute value becomes negative, so we have: - 4x = 15 + у + 314у = 25 + 4(3x - 1)

- Let's solve each case separately:

- Case 1: 3x - 1 ≥ 0 - Remove the absolute value: - 4x = 15 + у + 314у = 25 - 4(3x - 1) - 4x = 15 + у + 314у = 25 - 12x + 4

- Simplify: - 4x = 19 + у + 314у - 12x

- Combine like terms: - 16x = 19 + у + 314у

- Solve for x: - x = (19 + у + 314у) / 16

- Case 2: 3x - 1 < 0 - Remove the absolute value: - 4x = 15 + у + 314у = 25 + 4(3x - 1) - 4x = 15 + у + 314у = 25 + 12x - 4

- Simplify: - 4x = 19 + у + 314у + 12x

- Combine like terms: - -8x = 19 + у + 314у

- Solve for x: - x = (19 + у + 314у) / -8

So, the solutions for the equation 1 + 2(2,4 - 5x) + 7x = 1,8 + 2 + 17 + у + 314у = 14 + 3 + 17 - 4│3x - 1│ = 9 are: - x = (19 + у + 314у) / 16, when 3x - 1 ≥ 0 - x = (19 + у + 314у) / -8, when 3x - 1 < 0

Please note that the solutions may vary depending on the values of у and у.
