Question

17•у=357;у:18=45; 46-х=38.​

Answer 1

Ответ:

Пошаговое объяснение:

17•у=357;

y = 357 : 17

y = 21

у:18=45;

y = 45 * 18

y = 810

46-х=38.​

x = 46 - 38

x = 8

Answer 2

Let's solve the given equations step by step:

1. 17y = 357

To find the value of 'y,' we need to isolate it on one side of the equation. Divide both sides of the equation by 17:

17y/17 = 357/17

Simplifying:

y = 21

So, y equals 21.

2. y:18 = 45

To find the value of 'y,' we need to isolate it on one side of the equation. Multiply both sides of the equation by 18:

18 * (y/18) = 45 * 18

Simplifying:

y = 810

So, y equals 810.

3. 46 - x = 38

To find the value of 'x,' we need to isolate it on one side of the equation. Subtract 38 from both sides of the equation:

46 - x - 38 = 38 - 38

Simplifying:

8 - x = 0

To isolate 'x,' subtract 8 from both sides of the equation:

8 - x - 8 = 0 - 8

Simplifying:

-x = -8

Multiply both sides of the equation by -1 to get the positive value of 'x':

(-1) * (-x) = (-1) * (-8)

Simplifying:

x = 8

So, x equals 8.

To summarize: y = 21 y = 810 x = 8
