1 answer

To solve the equation \( 20 = d + 2d \), we will first combine like terms on the right side.

  1. Combine \( d \) and \( 2d \): \[ d + 2d = 3d \]

  2. Rewrite the equation: \[ 20 = 3d \]

  3. To solve for \( d \), divide both sides by 3: \[ d = \frac{20}{3} \]

Thus, the solution is: \[ d = \frac{20}{3} \text{ or approximately } 6.67 \]
