Answer 1

hope this helps! feel free to clarify

Answer 2

Answer:

$k = - 5$

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$−3(k+7)−5k+4=23 \\ (−3)(k)+(−3)(7)+−5k+4=23(Distribute) \\−3k+−21+−5k+4=23 \\ (−3k+−5k)+(−21+4)=23(Combine Like Terms) \\ −8k+−17=23 \\ −8k−17=23$

Step 2: Add 17 to both sides.

$−8k−17+17=23+17 \\ −8k=40$

Step 3: Divide both sides by -8.

$\frac{ - 8k}{ - 8}= \frac{40}{ - 8}$

$k = - 5$
