Question

1)-8x=72 2)0,9x=-5,43)-1,7x=-5,14)заранее спасибо)

Answer 1

1)-8х=72

х=-9

2)0,9х=-5,4

х=-6

3)-1,7х=-5,1

х=3

4)1/9х=-8/27

х=-8/3=-2 2/3

Answer 2

Let's solve each of the equations step by step:

1. -8x = 72

To solve this equation, we need to isolate the variable x. We can do that by dividing both sides of the equation by -8:

-8x / -8 = 72 / -8

This simplifies to:

x = -9

So the solution to the equation -8x = 72 is x = -9.

2. 0.9x = -5.4

To solve this equation, we need to isolate the variable x. We can do that by dividing both sides of the equation by 0.9:

0.9x / 0.9 = -5.4 / 0.9

This simplifies to:

x = -6

So the solution to the equation 0.9x = -5.4 is x = -6.

3. -1.7x = -5.1

To solve this equation, we need to isolate the variable x. We can do that by dividing both sides of the equation by -1.7:

(-1.7x) / -1.7 = -5.1 / -1.7

This simplifies to:

x = 3

So the solution to the equation -1.7x = -5.1 is x = 3.

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