f(0-6)=f(0)+f(6)

Solution for f(0-6)=f(0)+f(6) equation:

Simplifying
f(0 + -6) = f(0) + f(6)

Combine like terms: 0 + -6 = -6
f(-6) = f(0) + f(6)

Reorder the terms for easier multiplication:
-6f = f(0) + f(6)

Reorder the terms for easier multiplication:
-6f = 0f + f(6)

Anything times zero is zero.
-6f = 0f + f(6)

Reorder the terms for easier multiplication:
-6f = 0 + 6f
Remove the zero:
-6f = 6f

Solving
-6f = 6f

Solving for variable 'f'.

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

Add '-6f' to each side of the equation.
-6f + -6f = 6f + -6f

Combine like terms: -6f + -6f = -12f
-12f = 6f + -6f

Combine like terms: 6f + -6f = 0
-12f = 0

Divide each side by '-12'.
f = 0

Simplifying
f = 0
