Simplifying
-2f + K = 0

Reorder the terms:
K + -2f = 0

Solving
K + -2f = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1K' to each side of the equation.
K + -1K + -2f = 0 + -1K

Combine like terms: K + -1K = 0
0 + -2f = 0 + -1K
-2f = 0 + -1K
Remove the zero:
-2f = -1K

Add '2f' to each side of the equation.
-2f + 2f = -1K + 2f

Combine like terms: -2f + 2f = 0
0 = -1K + 2f

Simplifying
0 = -1K + 2f
