2(d-11)=18

1 answer

To solve the equation \( 2(d - 11) = 18 \), follow these steps:

  1. Start with the equation: \[ 2(d - 11) = 18 \]

  2. Divide both sides by 2 to simplify: \[ d - 11 = 9 \]

  3. Add 11 to both sides to solve for \( d \): \[ d = 9 + 11 \] \[ d = 20 \]

Thus, the solution is: \[ d = 20 \]
