-2 (-7k + 4) + 9 = -13
Use distributive property
14k - 8 + 9 = -13
Add 8 to both sides
14k + 9= -5
Subtract 9 from both sides
14k= -14
Divide 14 on both sides
Final Answer: k= -1

The answer is -1.
-2(-7k + 4) = -13 - 9
-2(-7k + 4) = -22
-7k + 4 = -22/2
-7k + 4 = 22/2
-7k + 4 = 11
-7k = 11 - 4
-7k = 7
k = -1.
