solve for f.\nf = -2 + \\frac{4}{5}f - 3\nf =

Explanation:

Step1: Combine like - terms on the right - hand side

$f=-5+\frac{4}{5}f$

Step2: Move terms with $f$ to one side

$f-\frac{4}{5}f=-5$

Step3: Simplify the left - hand side

$\frac{5f - 4f}{5}=-5$, which simplifies to $\frac{1}{5}f=-5$

Step4: Solve for $f$

Multiply both sides by 5: $f=-25$

Answer:

$-25$
