Answer:
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.
