Answer 1

Ответ:

Пошаговое объяснение:

1)-0,8х=-5,6;

Х=-5,6:(-0,8)

Х=7

2)-7х=4

Х=-4/7

3)-6х=-8;

Х=-8:(-6)

Х=1 1/3

4)-5х=30

Х=30:(-5)

Х=-6

Answer 2

Sure, let's solve the given equations:

1. -0.8x = -5.6

To solve for x, we need to isolate x on one side of the equation. To do that, we can divide both sides of the equation by -0.8:

x = -5.6 / -0.8

x = 7

So the solution for the first equation is x = 7.

2. -7x = 4

To solve for x, divide both sides by -7:

x = 4 / -7

x ≈ -0.57 (rounded to two decimal places)

So the solution for the second equation is x ≈ -0.57.

3. -6x = -8

To solve for x, divide both sides by -6:

x = -8 / -6

x ≈ 1.33 (rounded to two decimal places)

So the solution for the third equation is x ≈ 1.33.

4. -5x = 30

To solve for x, divide both sides by -5:

x = 30 / -5

x = -6

So the solution for the fourth equation is x = -6.

Here are the solutions for the given equations:

1. x = 7
2. x ≈ -0.57
3. x ≈ 1.33
4. x = -6
