Question

200 + (b + 400) = 1 000​

Answer 1

Ответ: b=400

Объяснение:

200+(b+400)=1000

b+400=1000-200

b+400=800

b=800-400

b=400

Answer 2

To solve the equation 200 + (b + 400) = 1000, we can follow these steps:

1. First, simplify the expression inside the parentheses: b + 400

2. Next, perform the addition within the parentheses: b + 400 = 400 + b

3. Rewrite the original equation with the simplified expression: 200 + (400 + b) = 1000

4. Combine like terms within the parentheses: 200 + 400 + b = 1000

5. Add the numbers outside the parentheses: 600 + b = 1000

6. To isolate the variable, subtract 600 from both sides of the equation: 600 + b - 600 = 1000 - 600 b = 400

Therefore, the value of b that satisfies the equation is 400.
