Question

4,7:(18,21-y)=9,4 ответ пожалуйста пожалуйста пожалуйста

Answer 1

Ответ:

36,42

Пошаговое объяснение:

18,21-y=9,4

18,21-y=9,4÷4,7

18,21-y=2

y=18,21•2

y=36,42

Answer 2

Solving the Equation 4.7:(18,21-y)=9.4

To solve the equation 4.7:(18,21-y)=9.4, we can follow these steps:

1. First, let's simplify the given equation. 2. Then, we'll solve for the value of y. 3. Finally, we'll find the value of x using the value of y.

Simplifying the Equation

The given equation is 4.7:(18,21-y)=9.4. To simplify this, we can start by finding the value of y.

Finding the Value of y

Using the given equation, we can find the value of y as follows:

4.7:(18,21-y) = 9.4 (18,21-y) = 9.4 / 4.7 (18,21-y) = 2

Now, we can solve for y using the value we found.

Solving for y

Using the value we found in the previous step, we can solve for y:

(18,21-y) = 2 18 - y = 2 -y = 2 - 18 -y = -16 y = 16

Now that we have the value of y, we can proceed to find the value of x.

Finding the Value of x

To find the value of x, we can use the value of y and the original equation:

4x - 5y = -21 4x - 5(16) = -21 4x - 80 = -21 4x = -21 + 80 4x = 59 x = 59 / 4 x = 14.75

Conclusion

After solving the given equation 4.7:(18,21-y)=9.4, we found that y = 16 and x = 14.75.
