Solve for f.
-4f – 3 = -8f + 9

f= 3

Step-by-step explanation:

-4f-3= -8f+9

The first thing to do is move the variable to one side. To do that, ad 8 to both sides, since -8 is the smallest number.

-4f-3= -8f+9

+8f    +8f

Next, add 3 to both sides.

4f-3= 9

  +3  +3

Now, isolate the variable by dividing by 4 to both sides.

4f= 12

4    4

This leaves you with f=3.
