Пошаговое объяснение:

111,11:(20,45-2,3x)-3,2=51

111,11:(20,45-2,3x)=51 + 3,2

111,11:(20,45-2,3x)=54,2

20,45-2,3х = 111,11 : 54,2

20,45-2,3х = 1111,1 : 542

20,45-2,3х = 2,05

2,3x = 20,45 - 2,05

2,3x = 18,4

x = 18,4 : 2,3

x = 184 : 23

x= 8.

Answer 3

To solve the equation 111,11:(20,45-2,3x)-3,2=51, let's break it down step by step.

Step 1: Simplify the expression inside the parentheses. 20,45 - 2,3x = 20,45 - 2.3x

Step 2: Perform the division. 111,11 / (20,45 - 2.3x) - 3,2 = 51

Step 3: Subtract 3.2 from both sides of the equation. 111,11 / (20,45 - 2.3x) = 51 + 3,2 111,11 / (20,45 - 2.3x) = 54,2

Step 4: Multiply both sides of the equation by (20,45 - 2.3x). 111,11 = 54,2 * (20,45 - 2.3x)

Step 5: Divide both sides of the equation by 54.2. 111,11 / 54,2 = 20,45 - 2.3x

Step 6: Simplify the left side of the equation. 2,050.45 = 20,45 - 2.3x

Step 7: Subtract 20.45 from both sides of the equation. 2,050.45 - 20,45 = -2.3x

Step 8: Simplify the left side of the equation. 2,030 = -2.3x

Step 9: Divide both sides of the equation by -2.3 to solve for x. x = 2,030 / -2.3

By performing the division, we can find the value of x.
