Subproblem 1
Set the factor '(6 + -1k)' equal to zero and attempt to solve:
Simplifying
6 + -1k = 0
Solving
6 + -1k = 0
Move all terms containing k to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + -1k = 0 + -6
Combine like terms: 6 + -6 = 0
0 + -1k = 0 + -6
-1k = 0 + -6
Combine like terms: 0 + -6 = -6
-1k = -6
Divide each side by '-1'.
k = 6
Simplifying
k = 6
