Question

200 + (b+ 400) = 1 000​

Answer 1

200+b+400=1000
600+b=1000
b=1000-600
b=400

Answer 2

To solve for the variable "b" in the equation:

200 + (b + 400) = 1000

You can start by simplifying the equation step by step:

1. First, simplify the expression within the parentheses:

b + 400

2. Now, substitute this simplified expression back into the equation:

200 + (b + 400) = 1000 becomes 200 + (b + 400) = 1000

3. Continue simplifying:

200 + (b + 400) = 1000

Now, combine like terms within the parentheses:

200 + b + 400 = 1000

4. Combine the constants on the left side of the equation:

200 + 400 = 600

So, the equation becomes:

b + 600 = 1000

5. To isolate the variable "b," subtract 600 from both sides of the equation:

b + 600 - 600 = 1000 - 600

This simplifies to:

b = 400

So, the solution to the equation is:

b = 400
