Question

solve $2d = 22$.
$d = \underline{\quad}$

Explanation:

Step1: Divide both sides by 2

To solve for \( d \) in the equation \( 2d = 22 \), we divide both sides of the equation by 2. This is based on the division property of equality, which states that if we divide both sides of an equation by the same non - zero number, the equality still holds.
\[
\frac{2d}{2}=\frac{22}{2}
\]

Step2: Simplify both sides

Simplifying the left - hand side, \( \frac{2d}{2}=d \) (because the 2 in the numerator and the 2 in the denominator cancel out). Simplifying the right - hand side, \( \frac{22}{2} = 11 \).

Answer:

\( d = 11 \)
