1+[2+x]=9

Answer 1

To solve the equation 1 + (2 + x) = 9, you can follow these steps:

1. Start by simplifying the equation inside the parentheses.

(2 + x) becomes 2 + x.

2. Now, substitute the simplified expression back into the original equation.

1 + (2 + x) = 9 becomes 1 + (2 + x) = 9.

3. Simplify the equation further.

1 + 2 + x = 9.

4. Combine like terms.

3 + x = 9.

5. Subtract 3 from both sides of the equation to isolate the x variable.

x = 9 - 3.

6. Perform the subtraction on the right side.

x = 6.

So, the solution to the equation 1 + (2 + x) = 9 is x = 6.
