Answer :
Answer:Simplifying
4f = 30 + -1f
Solving
4f = 30 + -1f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add 'f' to each side of the equation.
4f + f = 30 + -1f + f
Combine like terms: 4f + f = 5f
5f = 30 + -1f + f
Combine like terms: -1f + f = 0
5f = 30 + 0
5f = 30
Divide each side by '5'.
f = 6
