Answer 1

а последние примеры я не поняла, ты их как то не так написал и скобку где то забыл

Answer 2

$3(x - 2) = x + 2 \\ 3x - 6 = x + 2 \\ 2x = 8 \\ x = 4$

$5 - 2(x - 1) = 4 - x \\ 5 - 2x + 2 = 4 - x \\ - x = - 3 \\ x = 3$

$0.2(3x - 4) = 1.6(x - 2) \\ 0.6x - 0.4 = 1.6x - 3.2 \\ - x = - 2.8 \\ x = 2.8$

$2x + 0.1 - 4(1 - 4x) = 16x - 0.4 \\ 2x + 0.1 - 4 + 16x = 16x - 0.4 \\ 2x = 3.5 \\ x = 1.75$

Answer 3

Let's solve each equation step by step:

1. 3(x-2) = x+2

Expanding the equation: 3x - 6 = x + 2

Moving all x terms to one side and all constant terms to the other side: 3x - x = 2 + 6 2x = 8

Dividing both sides by 2 to isolate x: x = 8/2 x = 4

So the solution to the first equation is x = 4.

2. 5 - 2(x-1) = 4 - x

Expanding the equation: 5 - 2x + 2 = 4 - x

Combining like terms: 7 - 2x = 4 - x

Moving all x terms to one side and all constant terms to the other side: -2x + x = 4 - 7 -x = -3

Multiplying both sides by -1 to isolate x: x = 3

So the solution to the second equation is x = 3.

3. 2(3x-4) = 1.6(x-2)

Expanding the equation: 6x - 8 = 1.6x - 3.2

Moving all x terms to one side and all constant terms to the other side: 6x - 1.6x = -3.2 + 8 4.4x = 4.8

Dividing both sides by 4.4 to isolate x: x = 4.8/4.4 x ≈ 1.091

So the solution to the third equation is x ≈ 1.091.

4. 2x + 0.1 - 4(1 - 4x) = 16x - 0.4

Expanding and simplifying: 2x + 0.1 - 4 + 16x = 16x - 0.4

Combining like terms: 18x - 3.9 = 16x - 0.4

Moving all x terms to one side and all constant terms to the other side: 18x - 16x = -0.4 + 3.9 2x = 3.5

Dividing both sides by 2 to isolate x: x = 3.5/2 x = 1.75

So the solution to the fourth equation is x = 1.75.

I hope this helps! Let me know if you have any further questions.
