To solve the equation \( \frac{2f}{5} - \frac{8}{5} + 2f = 8 \), we will follow the properties of equality.
-
Combine like terms. We can rewrite \( 2f \) as \( \frac{10f}{5} \) to combine it with \( \frac{2f}{5} \): \[ \frac{2f}{5} + \frac{10f}{5} - \frac{8}{5} = 8 \]
This simplifies to: \[ \frac{12f}{5} - \frac{8}{5} = 8 \]
-
Clear the fractions by multiplying every term by 5: \[ 5 \left( \frac{12f}{5} \right) - 5 \left( \frac{8}{5} \right) = 5 \times 8 \] This simplifies to: \[ 12f - 8 = 40 \]
-
Add 8 to both sides: \[ 12f - 8 + 8 = 40 + 8 \] This simplifies to: \[ 12f = 48 \]
-
Divide by 12: \[ f = \frac{48}{12} \] This simplifies to: \[ f = 4 \]
Thus, the solution to the equation is \( f = 4 \).
Final Answer: 4
