To solve the equation \( 2f5 - 85 + 2f = 8 \), we can first clarify the equation a bit since it seems there might be a misunderstanding about the terms.
Let's assume \( f5 \) means \( 5f \) (as a coefficient of \( f \)). Thus, we can rewrite the equation as:
\[ 2(5f) - 85 + 2f = 8 \]
Now, simplifying the left side gives us:
\[ 10f - 85 + 2f = 8 \]
Combining like terms, we have:
\[ (10f + 2f) - 85 = 8 \]
This simplifies to:
\[ 12f - 85 = 8 \]
Next, we add \( 85 \) to both sides to isolate the term with \( f \):
\[ 12f = 8 + 85 \]
This simplifies to:
\[ 12f = 93 \]
Now, we divide both sides by \( 12 \) to solve for \( f \):
\[ f = \frac{93}{12} \]
This can be simplified. The greatest common divisor of \( 93 \) and \( 12 \) is \( 3 \):
\[ f = \frac{93 \div 3}{12 \div 3} = \frac{31}{4} \]
Thus, \( f = 7.75 \) or \( 7\frac{3}{4} \).
Since none of the other options in your responses seem to fit the value \( 7.75 \) or \( \frac{31}{4} \).
