Answer:

Answer: Adding 7 to both sides.

Step-by-step explanation:

You always do the "inverse" of the number without the variable next to it and either "add" or "subtract" it to the other side.

Ex: 7x - 3 = 18

In this case, you would add the 3 to the other side.

7x - 3 = 18

    + 3    +3

<u>7x</u> = <u>21</u>

7x    7x

<u><em>x = 3</em></u>
