Question

*The sum of a number and twice that number is 12.What is the number?*



​

Answer 1

Let the number be x

According to the question:

x+2x=12

3x=12

x=$\large\frac{12}{3}$

x=4

Therefore the number is,

$\huge\boxed{4}$

The sum of a number and twice that number is 12.What is the number?*

$\huge \fbox \green {answer}$

Let's consider that number to be 'x'..

So, twice the number (2x) is 12 greater than than the half of the number.

So the equation will be like,

2x=12+x/2

Solving this further,

2x=(24+x)/2

=> 4x=24+x

=>4x-x=24

=>3x=24

=>x=8

So the number is "8".
