3+6=9
6 is twice as much as 3
3+6=9
6 is twice as much as 3
now all you have to do is find the number from the steps above that has the tens digit as twice the ones digit
36
the answer is 36
The number is not 36, it is 63
"my tens digit is twice my ones digit" :
so, if the ones digit is x
then the tens digit is 2x
x+2x=9
3x=9
x=3
so the number is 63
"my tens digit is twice my ones digit" :
so, if the ones digit is x
then the tens digit is 2x
x+2x=9
3x=9
x=3
so the number is 63
Its 63
x then you put s in front then e in the middle
