(-d+2)-(-7d-4)

To simplify the expression \((-d + 2) - (-7d - 4)\), follow these steps:

1. Distribute the negative sign in front of the second parenthesis: \[ (-d + 2) + (7d + 4) \]

2. Now combine like terms:

   • Combine the \(d\) terms: \(-d + 7d = 6d\)
   • Combine the constant terms: \(2 + 4 = 6\)

3. So, the expression simplifies to: \[ 6d + 6 \]

The final simplified expression is: \[ 6d + 6 \]
