3-x=3x+5

To solve the equation \(3 - x = 3x + 5\), follow these steps:

1. Start by isolating the variable \(x\) on one side of the equation. You can do this by adding \(x\) to both sides:

   \[ 3 - x + x = 3x + 5 + x \]

   This simplifies to:

   \[ 3 = 4x + 5 \]

2. Next, subtract \(5\) from both sides to move the constant terms:

   \[ 3 - 5 = 4x + 5 - 5 \]

   This simplifies to:

   \[ -2 = 4x \]

3. Now, divide both sides by \(4\) to solve for \(x\):

   \[ x = \frac{-2}{4} \]

   Simplifying gives:

   \[ x = -\frac{1}{2} \]

So the solution to the equation \(3 - x = 3x + 5\) is \(x = -\frac{1}{2}\).
