Question

12+х=54. Х+1000=20000. 123+х=457. х+1234=7896

Answer 1

Ответ:

12+х=54

х=54-12

х=42

х+1000=20000

х=20000-1000

х=19000

123+х=457

х=457-123

х=334

х+1234=7896

х=7896-1234

х=6662

Answer 2

Ответ:

12+x=54

x=54-12

x=42

Пошаговое объяснение:

x+1000=20000

x=20000-1000

x=19000

123+x=457

x=457-123

x=334

x+1234=7896

x=7896-1234

x=6662

Answer 3

To solve each of these equations for x, you can follow these steps:

1. 12 + x = 54:

   Subtract 12 from both sides of the equation to isolate x:

   x = 54 - 12 x = 42

2. x + 1000 = 20000:

   Subtract 1000 from both sides of the equation to isolate x:

   x = 20000 - 1000 x = 19000

3. 123 + x = 457:

   Subtract 123 from both sides of the equation to isolate x:

   x = 457 - 123 x = 334

4. x + 1234 = 7896:

   Subtract 1234 from both sides of the equation to isolate x:

   x = 7896 - 1234 x = 6662

So, the solutions for x in these equations are:

1. x = 42
2. x = 19000
3. x = 334
4. x = 6662
