-3x-8=3x-8 this equations have one solution

Let's solve the equation \(-3x - 8 = 3x - 8\) step by step:

1. Add \(3x\) to both sides to move all the \(x\) terms to one side:

   \[ -3x + 3x - 8 = 3x + 3x - 8 \]

   This simplifies to:

   \[ -8 = 6x - 8 \]

2. Add \(8\) to both sides to isolate the \(x\) term:

   \[ -8 + 8 = 6x - 8 + 8 \]

   This simplifies to:

   \[ 0 = 6x \]

3. Divide both sides by \(6\) to solve for \(x\):

   \[ x = 0 \]

Thus, the equation \(-3x - 8 = 3x - 8\) has one solution, which is \(x = 0\).
