Solving for variable 'k'.

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

Add '(3k)' to each side of the equation.
20 + -1k + (3k) = (-3k) + (3k)

Combine like terms: -1k + (3k) = 2k
20 + 2k = (-3k) + (3k)

Combine like terms: (-3k) + (3k) = 0
20 + 2k = 0

Add '-20' to each side of the equation.
20 + -20 + 2k = 0 + -20

Combine like terms: 20 + -20 = 0
0 + 2k = 0 + -20
2k = 0 + -20

Combine like terms: 0 + -20 = -20
2k = -20

Divide each side by '2'.
k = -10

Simplifying
k = -10
