Answer 1

Answer:

$f = - \frac{5}{3}$

Step-by-step explanation:

$\frac{ - 3f}{4} = \frac{5}{4} \\ cross \: \: multipication \\ - 12f = 20 \\ \frac{ - 12f}{ - 12} = \frac{20}{ - 12} \\ f = \frac{20}{ - 12} \\ f = - \frac{5}{3}$

hope this helps

good luck! have a nice day!

Answer 2

Answer:

$f=-\frac{5}{3}$

Step-by-step explanation:

$-\frac{3}{4}f=\frac{5}{4}$

$(4)-\frac{3}{4}f=(4)\frac{5}{4}$

$-3f=5$

$\frac{-3f}{-3}=\frac{5}{-3}$

$f=-\frac{5}{3}$
