To solve the equation \(-5 = 6d - 7d + 4\), we can start by simplifying the right-hand side. 1. Combine like terms: \[ 6d - 7d = -1d \quad \text{(or simply } -d\text{)} \] So the equation becomes: \[ -5 = -d + 4 \] 2. Now, we can isolate \(-d\) by subtracting 4 from both sides: \[ -5 - 4 = -d \] \[ -9 = -d \] 3. To solve for \(d\), multiply both sides by -1: \[ d = 9 \] Thus, the solution is: \[ \boxed{9} \]

-5= 6d-7d+4

To solve the equation \(-5 = 6d - 7d + 4\), we can start by simplifying the right-hand side.

Combine like terms: \[ 6d - 7d = -1d \quad \text{(or simply } -d\text{)} \] So the equation becomes: \[ -5 = -d + 4 \]
Now, we can isolate \(-d\) by subtracting 4 from both sides: \[ -5 - 4 = -d \] \[ -9 = -d \]
To solve for \(d\), multiply both sides by -1: \[ d = 9 \]

Thus, the solution is: \[ \boxed{9} \]
