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:
\[
d = \frac{20}{3} \text{ or approximately } 6.67
\]
