now do 7b-b-x+5-2x-7b combining like terms

To combine like terms in the expression \(7b - b - x + 5 - 2x - 7b\), follow these steps:

1. **Identify like terms**:
   - The terms involving \(b\) are \(7b\), \(-b\), and \(-7b\).
   - The terms involving \(x\) are \(-x\) and \(-2x\).
   - The constant term is \(5\).

2. **Combine the like terms**:
   - For \(b\): \(7b - b - 7b = 6b - 7b = -b\)
   - For \(x\): \(-x - 2x = -3x\)
   - The constant term remains \(5\).

3. **Write the simplified expression**:
   \[
   -b - 3x + 5
   \]

So, the simplified expression is \(-b - 3x + 5\).
