Question

1) -1,2x=-3,6 1) 1/3:x-2/9

Answer 1

Объяснение:

1)-1,2x=-3,6

x=-3,6:1,2

x=-3

2)1/3:x=2/9

x=2/9*(-3/1)

x=-2/3

Answer 2

It appears that you have two equations here. Let's solve each one step by step:

1. -1 + 2x = -3.6

To solve for x, we need to isolate x on one side of the equation. First, let's get rid of the constant term (-1) on the left side by adding 1 to both sides:

-1 + 2x + 1 = -3.6 + 1

This simplifies to:

2x = -2.6

Next, we want to isolate x, so we divide both sides by 2:

2x / 2 = -2.6 / 2

x = -1.3

So the solution to the first equation is x = -1.3.

2. (1/3)x - 2/9

There's an equal sign missing in this equation, so I assume it's set to zero:

(1/3)x - 2/9 = 0

To solve for x, we need to isolate x on one side of the equation. First, let's get rid of the constant term (-2/9) on the left side by adding 2/9 to both sides:

(1/3)x - 2/9 + 2/9 = 0 + 2/9

This simplifies to:

(1/3)x = 2/9

Next, we want to isolate x, so we multiply both sides by 3 (to get rid of the fraction 1/3):

3 * (1/3)x = 3 * (2/9)

This simplifies to:

x = 6/9

Now, we can simplify the fraction 6/9 by dividing both the numerator and denominator by their greatest common divisor, which is 3:

x = 2/3

So the solution to the second equation is x = 2/3.

To summarize:

1. x = -1.3
2. x = 2/3
