To rewrite the equation \( f + s = 16 \) in terms of \( f \), you can isolate \( f \) on one side of the equation. Here’s how you can do it:
Starting with the equation:
\[ f + s = 16 \]
Subtract \( s \) from both sides:
\[ f = 16 - s \]
So, the equation rewritten in terms of \( f \) is:
\[ f = 16 - s \]
