Your question can be reworded as
? X 3 = 20.
All you do is divide by 3 on both sides to isolate the x. It basically looks like a magician makes the 3 disappear and then appear on the other side.
\(\frac{?\times 3}{3} = \frac{20}{3}\)
\(?= \frac{20}{3}\)
Tadah! We have mathmagically found the answer.
The answer is \(\boxed{ \frac{20}{3}}\boxed\) in fraction form or \(\boxed{6.66}\boxed\) in decimal form.
