Answer:
a. 2n = 3n − 12, 12
Step-by-step explanation:
Let the number be represented by n.
Then 2 times the number is 2*n = 2n
3 times the number = 3*n = 3n
12 minus 3 times the number is 3n-12
It is given that 2 times the number is the same as 12 minus 3 times the number.
Expressing this equation form:
![\[2n=3n-12\]](https://tex.z-dn.net/?f=%5C%5B2n%3D3n-12%5C%5D)
Solving the equation,
![\[3n-2n=12\]](https://tex.z-dn.net/?f=%5C%5B3n-2n%3D12%5C%5D)
![\[=> n=12\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E%20n%3D12%5C%5D)
Hence the required number is 12.
