Answer:
x + 2x = 21
Or
3x = 21
Step-by-step explanation:
Let the required number be x.
Two times of the number = 2x
Above statement in Mathematical form can be expressed as:
![x + 2x = 21 \\ \implies \: 3x = 21](https://tex.z-dn.net/?f=x%20%2B%202x%20%3D%2021%20%5C%5C%20%20%5Cimplies%20%5C%3A%203x%20%3D%2021)
