Answer 1

C-300=600

C=600+300

C=900

Проверка:

900-300=600

600=600

200+x=900

X=900-200

X=700

Проверка:

200+700=900

900=900

800-X=200

X=800-200

X=600

Проверка:

800-600=200

200=200

Answer 2

С-300=600 => 600+300=900 => С=900

200+Х=900 => 900-200=700 => Х=700

800-Х=200 => 800-200=600 => Х=600

Answer 3

To solve these equations, let's represent the unknown values with the variable "x." Then we can proceed with the calculations:

1. C - 300 = 600 Adding 300 to both sides to isolate C: C = 600 + 300 C = 900

2. 200 + x = 900 Subtracting 200 from both sides to isolate x: x = 900 - 200 x = 700

3. 800 - x = 200 Subtracting 800 from both sides to isolate x: -x = 200 - 800 -x = -600

Since we have -x = -600, multiplying both sides by -1 to solve for x: x = 600

So the values of the variables are: C = 900 x = 700 x = 600
