2 + k = 6k
So minus k from each side gives us
2 = 5k
Then we can divide by 5 to find what k is (2/5)

You know that and

Since you know that is a fraction of you can write such that

Therefore

You can then compare the component and component to get a pair of simultaneous equations with two unknowns. You're not looking for so you can eliminate it and solve for
