Question

1)-5x=30; 2)-0,8x=-5,6; 3)-7x=4; 4)-6x=-8; ​

Answer 1

1) -5х = 30

х= 30+5

х=35

2)-0,8х= -5,6

х= -5,6+0,8

х= -4,8

3) -7х=4

х= 4+7

х= 11

4) -6х= -8

х= -8+6

х= -2

Answer 2

Відповідь:

1)х=-6 2)х=7 3)не виходить або 4/7 4)х=8/6

Answer 3

Let's solve each equation step by step:

1. -5x = 30

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by -5:

-5x / -5 = 30 / -5

x = -6

So the solution to this equation is x = -6.

2. -0.8x = -5.6

To solve for x, we'll divide both sides of the equation by -0.8:

-0.8x / -0.8 = -5.6 / -0.8

x = 7

The solution to this equation is x = 7.

3. -7x = 4

To solve for x, we'll divide both sides of the equation by -7:

-7x / -7 = 4 / -7

x = -4/7

The solution to this equation is x = -4/7.

4. -6x = -8

To solve for x, we'll divide both sides of the equation by -6:

-6x / -6 = -8 / -6

x = 4/3

The solution to this equation is x = 4/3.
