To solve for B in the equation \( A = BC - D \), we can follow these steps:
Step 1: Add D to both sides.
Explanation: This isolates the term containing B on one side.
Simplifies to:
\[ A + D = BC \]
Step 2: Divide both sides by C.
Explanation: This isolates B by eliminating C from the right side of the equation.
Simplifies to:
\[ B = \frac{A + D}{C} \]
Final Solution:
The solution for B is:
\[ B = \frac{A + D}{C} \]
