А. 7 ( x - 2 ) = x - 2 б. 6x - 3 = x - 1,5 в. 11x - 5 = 10 ( x - 4 )г. 4 ( x + 0,5 ) = x - 0,7РОЗПИСАТЬ СРОЧНО ПОЖАЛУЙСТА ​

Answer 1

А. 7(x-2) = x-2
7x - 14 = x - 2
6x = 12
x = 2

б. 6x - 3 = x - 1.5
5x = 1.5
x = 0.3

в. 11x - 5 = 10(x-4)
11x - 5 = 10x - 40
x = -35

г. 4(x+0.5) = x - 0.7
4x + 2 = x - 0.7
3x = -2.7
x = -0.9

Answer 2

а. 7(x - 2) = x - 2

Let's solve this equation step by step:

1. Distribute the 7 on the left side: 7x - 14 = x - 2

2. Move the x term to the left side by subtracting x from both sides: 7x - x - 14 = -2

Simplifying the left side gives: 6x - 14 = -2

3. Move the constant term (-14) to the right side by adding 14 to both sides: 6x = -2 + 14

Simplifying the right side gives: 6x = 12

4. Finally, divide both sides by 6 to isolate x: x = 12 / 6

Simplifying the right side gives the solution: x = 2

Therefore, the solution to the equation is x = 2.

б. 6x - 3 = x - 1.5

Let's solve this equation step by step:

1. Move the x term to the left side by subtracting x from both sides: 6x - x - 3 = -1.5

Simplifying the left side gives: 5x - 3 = -1.5

2. Move the constant term (-3) to the right side by adding 3 to both sides: 5x = -1.5 + 3

Simplifying the right side gives: 5x = 1.5

3. Finally, divide both sides by 5 to isolate x: x = 1.5 / 5

Simplifying the right side gives the solution: x = 0.3

Therefore, the solution to the equation is x = 0.3.

в. 11x - 5 = 10(x - 4)

Let's solve this equation step by step:

1. Distribute the 10 on the right side: 11x - 5 = 10x - 40

2. Move the 10x term to the left side by subtracting 10x from both sides: 11x - 10x - 5 = -40

Simplifying the left side gives: x - 5 = -40

3. Move the constant term (-5) to the right side by adding 5 to both sides: x = -40 + 5

Simplifying the right side gives: x = -35

Therefore, the solution to the equation is x = -35.

г. 4(x + 0.5) = x - 0.7

Let's solve this equation step by step:

1. Distribute the 4 on the left side: 4x + 2 = x - 0.7

2. Move the x term to the left side by subtracting x from both sides: 4x - x + 2 = -0.7

Simplifying the left side gives: 3x + 2 = -0.7

3. Move the constant term (2) to the right side by subtracting 2 from both sides: 3x = -0.7 - 2

Simplifying the right side gives: 3x = -2.7

4. Finally, divide both sides by 3 to isolate x: x = -2.7 / 3

Simplifying the right side gives the solution: x = -0.9

Therefore, the solution to the equation is x = -0.9.

I hope this helps!
