Question

800-a=668 100+x=1000

Answer 1

Пошаговое объяснение:

$800 - a = 668 \\ - a = 668 - 800 \\ - a = - 132 \\ a = 132 \\ \\ 100 + x = 1000 \\ x = 1000 - 100 \\ x = 900$

Answer 2

800-а=668 100+x=1000 1000-100=900 900+100=1000

800-668

а=132

Answer 3

To solve these equations for the variables "a" and "x," you can follow these steps:

1. Solve the first equation for "a": 800 - a = 668

   Subtract 668 from both sides to isolate "a": 800 - 668 = a

   Simplify the left side: 132 = a

   So, a = 132.

2. Solve the second equation for "x": 100 + x = 1000

   Subtract 100 from both sides to isolate "x": x = 1000 - 100

   Simplify the right side: x = 900

   So, x = 900.

The solutions are: a = 132 x = 900
