Question

-82,8:(43,1-x*(-0,09))=18 20 баллов!!!!

Answer 1

-82,8:(43,1-x*(-0,09))=18

-82,8:(43,1+0,09х)=18

18(43,1+0,09х)=-82,8

1,62х=-82,8-775,8

1,62х=-858,6

х=-530

Answer 2

To solve the equation, we need to find the value of "x." Let's break down the equation step by step:

-82,8: (43,1 - x * (-0,09)) = 18

1. First, let's simplify the expression inside the parenthesis: 43.1 - x * (-0.09)

Since we are subtracting a negative value (x * (-0.09)), it is equivalent to adding a positive value (0.09x):

43.1 + 0.09x

2. Now, the equation becomes: -82.8 ÷ (43.1 + 0.09x) = 18

3. Next, let's isolate the term containing "x" by getting rid of the fraction. To do that, multiply both sides by (43.1 + 0.09x):

-82.8 = 18 * (43.1 + 0.09x)

4. Distribute the 18 on the right side:

-82.8 = 773.8 + 1.62x

5. Now, let's isolate the term containing "x" on one side. To do that, subtract 773.8 from both sides:

-82.8 - 773.8 = 1.62x

6. Simplify the left side:

-856.6 = 1.62x

7. Finally, divide by 1.62 to solve for "x":

x = -856.6 / 1.62

x ≈ -529.01234568

So, the value of "x" that satisfies the equation is approximately -529.01234568.
