To solve the equation \(\frac{2f}{5} - \frac{8}{5} + 2f = 8\), follow these steps:
1. First, combine like terms. Rewrite \(2f\) as \(\frac{10f}{5}\) to get a common denominator:
\[
\frac{2f}{5} + \frac{10f}{5} - \frac{8}{5} = 8
\]
This simplifies to:
\[
\frac{12f - 8}{5} = 8
\]
2. To eliminate the fraction, multiply both sides by 5:
\[
12f - 8 = 40
\]
3. Next, isolate the term with \(f\) by adding 8 to both sides:
\[
12f = 48
\]
4. Finally, divide both sides by 12:
\[
f = 4
\]
Thus, the solution to the equation is \(f = 4\).
So, the response is **4**.
