A number added to a number twice as big is thirty-three. What is the larger number

Question

Im confused about this question because I was in class And I didn't understand it

Answer 1

n + 2n = 33

 

3n= 33

 

divide by 3

 

n= 11

 

You can check this by saying that if n=11, a number twice as big would be 22.  11+22=33
