Answer:

k = - 5

Step-by-step 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

5x-2=3x+8 must find what X is equal to
serious [3.7K]
I had homework on this today lol

First, add 2 to both sides. It would then be 5x = 3x + 10. Then subtract 3x from both sides and you would end up with 2x = 10. Divide 2x by 2 and the 10 by 2. The answer is x = 5.
