Answer:

k = - 5

Explanation:

Given

240 = 8(- 5 - 7k) ← divide both sides by the multiplier 8

30 = - 5 - 7k ( add 5 to both sides )

35 = - 7k ( divide both sides by - 7 )

- 5 = k

240 = 8 (-5 - 7k)

First, we can distribute.

240 = -40 - 56k

+40 +40 ← add 40 on both sides.

280 = -56k

-56 -56 ← divide both sides by -56

-5 = k
