Answer:
Step-by-step explanation:
Simplifying
3f + f + 4f = 0
Combine like terms: 3f + f = 4f
4f + 4f = 0
Combine like terms: 4f + 4f = 8f
8f = 0
Solving
8f = 0
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '8'.
f = 0
Simplifying
f = 0
