Respuesta :

F= -1 2/3 or 5/3

In order to find the answer all you have to do is multiply both sides by -4/3.

-3/4f × -4/3 = f

-4/3 × 5/4 = -20/12

-20/12 simplified is -5/3 or -1 2/3

Answer:

f = -5/3.

Step-by-step explanation:

We want to isolate f on the left side of the equation.

To do this we multiply both sides by -4/3 , because -3/4 * -4/3 = 1 giving  us 1f.

-4/3 * -3/4 f = 5/4 * -4/3

-12/-12 f = 5/4 * -4/3

1 f =  -20/12

f = - 5/3.
