Question

For what integer value of `k` does `2k+4=3k`?

Answer 1

`k=4`

Explanation:

You can solve this equation by inspection by comparing the left and right sides.

On the left there are `2k`'s and a number. On the right there are `3k`'s

The number `(4)` must therefore be equal to `k`, so that we have

`3k = 3k`

Consider it as:
`2k +4 = 3k`

`2k+4 = 2k + k`

`:. k=4`
