Question

How do you solve `42= 7y`?

Answer 1

See below.

Explanation:

To solve this, you must use division. If `7y=42`, then you can think about what times 7 is equal to 42. But, an easier way to do this, is the following way.

First, divide the side that has `7y` by `7`.

`(7y)/7=42`

Now, divide the `42` by `7` as what is done to one side must be done to the other.

`y=42/7`

After solving that division problem, you know that `42-:7=6`.

`y=6`

Therefore, `y` is equal to `6`.
