Answer:
x = 21

= 3
Our goal is to get x by itself. We can see that it is currently being divided by 7. So, we can multiply it by 7. Remember, what you do to one side of an equation, you must do to the other.
7 ·

The 7s on the left side of the equation wil cancel each other out, leaving us with x.
x = 3 · 7
Multiply 3 and 7.
x = 21
