Answer 1

Ответ:

1) 8 + x = -11

x = -11 - 8

x = -19

2)x - 2,6 = -6,4

x = -6,4 + -2,6

x = -9

3)0,35x = -0,7

x = -0,7 : 0,35

x = -2

4)x : (-2,5) = 15

x = -2,5 * 15

x = -37,5

5)-8,4
6)

Answer 3

1) 8 + x = -11

To solve the equation 8 + x = -11, we need to isolate the variable x.

Subtracting 8 from both sides of the equation, we get:

x = -11 - 8

Simplifying the right side of the equation, we have:

x = -19

Therefore, the solution to the equation 8 + x = -11 is x = -19.

2) x - 2.6 = -6.4

To solve the equation x - 2.6 = -6.4, we need to isolate the variable x.

Adding 2.6 to both sides of the equation, we get:

x = -6.4 + 2.6

Simplifying the right side of the equation, we have:

x = -3.8

Therefore, the solution to the equation x - 2.6 = -6.4 is x = -3.8.

3) 0.35 + x = -0.7

To solve the equation 0.35 + x = -0.7, we need to isolate the variable x.

Subtracting 0.35 from both sides of the equation, we get:

x = -0.7 - 0.35

Simplifying the right side of the equation, we have:

x = -1.05

Therefore, the solution to the equation 0.35 + x = -0.7 is x = -1.05.

4) x: (-2.5) = 15

To solve the equation x / (-2.5) = 15, we need to isolate the variable x.

Multiplying both sides of the equation by -2.5, we get:

x = 15 * (-2.5)

Simplifying the right side of the equation, we have:

x = -37.5

Therefore, the solution to the equation x / (-2.5) = 15 is x = -37.5.

5) (-1.4) + x = 7

To solve the equation (-1.4) + x = 7, we need to isolate the variable x.

Subtracting (-1.4) from both sides of the equation, we get:

x = 7 - (-1.4)

Simplifying the right side of the equation, we have:

x = 7 + 1.4

x = 8.4

Therefore, the solution to the equation (-1.4) + x = 7 is x = 8.4.

6) 4.6 : x = -23

To solve the equation 4.6 / x = -23, we need to isolate the variable x.

Multiplying both sides of the equation by x, we get:

4.6 = -23 * x

Dividing both sides of the equation by -23, we get:

x = 4.6 / (-23)

Simplifying the right side of the equation, we have:

x = -0.2

Therefore, the solution to the equation 4.6 / x = -23 is x = -0.2.

7) 8.6x - 5 = 5.1x + 2

To solve the equation 8.6x - 5 = 5.1x + 2, we need to isolate the variable x.

Subtracting 5.1x from both sides of the equation, we get:

8.6x - 5.1x - 5 = 2

Combining like terms, we have:

3.5x - 5 = 2

Adding 5 to both sides of the equation, we get:

3.5x = 2 + 5

Simplifying the right side of the equation, we have:

3.5x = 7

Dividing both sides of the equation by 3.5, we get:

x = 7 / 3.5

Simplifying the right side of the equation, we have:

x = 2

Therefore, the solution to the equation 8.6x - 5 = 5.1x + 2 is x = 2.

8) 2.4 + x: (-0.2) = -0.2 + (-1.8)

To solve the equation 2.4 + x / (-0.2) = -0.2 + (-1.8), we need to isolate the variable x.

Multiplying both sides of the equation by (-0.2), we get:

2.4 * (-0.2) + x = (-0.2 + (-1.8)) * (-0.2)

Simplifying the left side of the equation, we have:

-0.48 + x = (-2) * (-0.2)

Simplifying the right side of the equation, we have:

-0.48 + x = 0.4

Subtracting -0.48 from both sides of the equation, we get:

x = 0.4 - (-0.48)

Simplifying the right side of the equation, we have:

x = 0.4 + 0.48

x = 0.88

Therefore, the solution to the equation 2.4 + x / (-0.2) = -0.2 + (-1.8) is x = 0.88.
