To solve the equation \( \frac{2f}{5} - \frac{8}{5} + 2f = 8 \), we can first eliminate the fractions by multiplying the entire equation by 5:
\[
5\left(\frac{2f}{5}\right) - 5\left(\frac{8}{5}\right) + 5(2f) = 5(8)
\]
This simplifies to:
\[
2f - 8 + 10f = 40
\]
Now combine the like terms (\(2f\) and \(10f\)):
\[
12f - 8 = 40
\]
Next, add 8 to both sides to isolate the term with \(f\):
\[
12f = 48
\]
Now, divide both sides by 12:
\[
f = \frac{48}{12} = 4
\]
The solution is \( f = 4 \).
Thus, the correct response is **4**.
\[
5\left(\frac{2f}{5}\right) - 5\left(\frac{8}{5}\right) + 5(2f) = 5(8)
\]
This simplifies to:
\[
2f - 8 + 10f = 40
\]
Now combine the like terms (\(2f\) and \(10f\)):
\[
12f - 8 = 40
\]
Next, add 8 to both sides to isolate the term with \(f\):
\[
12f = 48
\]
Now, divide both sides by 12:
\[
f = \frac{48}{12} = 4
\]
The solution is \( f = 4 \).
Thus, the correct response is **4**.
