To determine if \( r = 48 \) is a solution to the equation
\[ 24 = \frac{r}{2} \]
we can substitute \( r = 48 \) into the equation.
Substituting gives:
\[ 24 = \frac{48}{2} \]
Now, simplify the right side:
\[ \frac{48}{2} = 24 \]
This means the equation becomes:
\[ 24 = 24 \]
Since both sides are equal, \( r = 48 \) is indeed a solution to the equation.
