Question

How do you solve `4k-27=15k-18`?

Answer 1

`k = -9/11`

Explanation:

`4k - 27 = 15k - 18`

`4k - 15k = -18 + 27`

`-11k = 9`

`k = -9/11`

First, bring all like terms onto the same side, so bring the `x` terms onto the left and the numbers by themselves onto the right. Then simplify. Then you need to get `k` on its own on the left so you divide both sides by `-11`.

Therefore,

`k = -9/11`
