k + n + m = 0

Reorder the terms:
k + m + n = 0

Solving
k + m + n = 0

Solving for variable 'k'.

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

Add '-1m' to each side of the equation.
k + m + -1m + n = 0 + -1m

Combine like terms: m + -1m = 0
k + 0 + n = 0 + -1m
k + n = 0 + -1m
Remove the zero:
k + n = -1m

Add '-1n' to each side of the equation.
k + n + -1n = -1m + -1n

Combine like terms: n + -1n = 0
k + 0 = -1m + -1n
k = -1m + -1n

Simplifying
k = -1m + -1n
