Explanation:

Use the Distributive Property:


3k - 4k + 8 = 14k - 22


- k + 8 = 14k - 22

Add k to both sides:


8 = 15k - 22

Add 22 to both sides:


30 = 15k

Divide each side by 15:


2 = k

Answer:

k=2

Explanation:

Expanding gives


3k-4k+8=14k-22.

Further simplification yields


-k+8=14k-22


15k=30


k=2.
