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.

7y7=42

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

y=427

After solving that division problem, you know that 42รท7=6.

y=6

Therefore, y is equal to 6.
