Answer:
f = 1
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other.
Add 3f and subtract 2 from both sides:
-f + 2 (-2) + 4f (+3f) = 8 (-2) - 3f (+3f)
-f + 4f + 3f = 8 - 2
Simplify:
(-f + 7f) = 6
7f - f = 6
6f = 6
Isolate the variable, f. Divide 6 from both sides:
(6f)/6 = (6)/6
f = 6/6
f = 1
1 is your answer for f.
