Answer:
Simplifying
6f + -12 = 4f + 6
Reorder the terms:
-12 + 6f = 4f + 6
Reorder the terms:
-12 + 6f = 6 + 4f
Solving
-12 + 6f = 6 + 4f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-4f' to each side of the equation.
-12 + 6f + -4f = 6 + 4f + -4f
Combine like terms: 6f + -4f = 2f
-12 + 2f = 6 + 4f + -4f
Combine like terms: 4f + -4f = 0
-12 + 2f = 6 + 0
-12 + 2f = 6
Add '12' to each side of the equation.
-12 + 12 + 2f = 6 + 12
Combine like terms: -12 + 12 = 0
0 + 2f = 6 + 12
2f = 6 + 12
Combine like terms: 6 + 12 = 18
2f = 18
Divide each side by '2'.
f = 9
Simplifying
f = 9
