Answer:
k = 2
Step-by-step explanation:
5k = 6k + 4 - 6
We can simplify this by solving 4 - 6 (replacing it with -2 !)
5k = 6k - 2
Now we can subtract 5k from both sides.
0 = k - 2
Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.
2 = k
Just reversing it...
k = 2
Answer: k = 2
