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.
[tex] \frac{?\times 3}{3} = \frac{20}{3}[/tex]
[tex]?= \frac{20}{3} [/tex]
Tadah! We have mathmagically found the answer.
The answer is [tex]\boxed{ \frac{20}{3}}\boxed[/tex] in fraction form or [tex]\boxed{6.66}\boxed[/tex] in decimal form.
