a_(b+c)-(a+__)+c

Answer 1

To simplify the expression \( a_{(b+c)} - (a + __) + c \), we can follow these steps:

1. Replace \( __ \) with a variable (let's call it \( x \)) to make it easier to work with:
   The expression becomes \( a_{(b+c)} - (a + x) + c \).

2. Distributing the negative sign: \( a_{(b+c)} - a - x + c \).

3. If the intention is to reformat or simplify further, please specify what you would like to achieve (e.g., collecting like terms, factoring, etc.).

If you need to determine a specific value for \( x \) or to clear up any confusion, please provide additional context!
