Question

7 x (4217-c)=9163. 560:x=240:3. 240:(y-18)=8. Срочно!:)

Answer 1

7 * (4217-c)=9163
4217-с=9163:7
4217-с=1309
с=4217-1309
с=2908


560:х=240:3
560:х=80
х=560:80
х=7

240:(у-18)=8
y-18=240:8
y-18=30
y=48

Answer 2

Solving the Equations:

Let's solve the given equations step by step.

1. 7x + (4217 - c) = 9163: To solve for x, we can start by isolating the term with x on one side of the equation. ``` 7x + (4217 - c) = 9163 7x = 9163 - 4217 + c 7x = 4946 + c x = (4946 + c) / 7 ```

2. 560 ÷ x = 240 ÷ 3: To solve for x, we can cross-multiply and then solve for x. ``` 560 * 3 = 240 * x 1680 = 240x x = 1680 / 240 x = 7 ```

3. 240 ÷ (y - 18) = 8: To solve for y, we can isolate the term with y on one side of the equation. ``` 240 = 8(y - 18) 240 = 8y - 144 8y = 240 + 144 8y = 384 y = 384 / 8 y = 48 ```

Solutions:

1. 7x + (4217 - c) = 9163: - The solution for x is x = (4946 + c) / 7.

2. 560 ÷ x = 240 ÷ 3: - The solution for x is x = 7.

3. 240 ÷ (y - 18) = 8: - The solution for y is y = 48.
