Question

One number is 3 more than another. The larger number is twice the smaller number. What is the smaller number ?

Answer 1

3 and 6

Explanation:

Lets define the smaller number as x.

The larger number is twice the smaller number, therefore the larger number is 2x.

It is given that the larger number is 3 more than the smaller number.

2x - x = 3

x = 3

The smaller number is x which is 3.

The larger number is 2x which is 2(3), that is 6.

Answer 2

3

Explanation:

First number( the smaller number) is x, second number is (x+3).

Larger number (x+3), and it is twice the smaller number (x),

so

x+3=2x

2x-x=3

x=3
