Answer:

a. 2n = 3n − 12, 12

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:


\[2n=3n-12\]

Solving the equation,


\[3n-2n=12\]


\[=> n=12\]

Hence the required number is 12.
