Question

solve 3d = 12

Explanation:

Step1: Isolate the variable

To solve for \( d \) in the equation \( 3d = 12 \), we need to isolate \( d \). We can do this by dividing both sides of the equation by 3.
\[
\frac{3d}{3}=\frac{12}{3}
\]

Step2: Simplify both sides

Simplifying the left side, \( \frac{3d}{3} \) simplifies to \( d \). Simplifying the right side, \( \frac{12}{3} = 4 \).

Answer:

\( d = 4 \)
