To eliminate \(-10f\) from the right side of the equation, we can indeed add \(10f\) to both sides. Let's do this step by step:
Starting with the original equation:
\[ 22f - 10 = -10f - 8 \]
Now, add \(10f\) to both sides:
\[ 22f - 10 + 10f = -10f - 8 + 10f \]
This simplifies to:
\[ (22f + 10f) - 10 = -8 \]
So now we have:
\[ 32f - 10 = -8 \]
Now the \(f\) terms are only on the left side of the equation.
