Question: Show step by step for $B$
1. The problem is to solve or analyze the expression or equation involving $B$.
2. Since the user only mentioned $B$ without additional context, we assume $B$ is a variable or part of an equation.
3. If $B$ is part of an equation, identify the equation and isolate $B$.
4. For example, if the equation is $A = B + C$, to solve for $B$, subtract $C$ from both sides:
$$A = B + C$$
$$A - C = B + \cancel{C} - \cancel{C}$$
$$B = A - C$$
5. This shows how to isolate $B$ step by step.
6. Without more context, this is the general approach to handle $B$ in an equation.
