Is 1,2,3,6,9 and 36 a múltiple of 9?

1 is not a multiple of 9.
2 is not a multiple of 9.
3 is not.
6 isn't either.

9 is a multiple of 9 because 9 x 1 = 9.
36 is a multiple of 9 because 9 x 4 = 36.

1 Is not a multiple of 9, nothing times 9 is 1.
2 Is not a multiple of 9, nothing times 9 gives 2.
3 Is not a multiple of 9, nothing times 9 gives 3.
6 Is not a multiple of 9, nothing times 9 is 6.
Those numbers are all less than 9.

9 is a multiple of 9 because 9 x 1 = 9.
36 is a multiple of 9 because 9 x 4 = 36.

The correct answer is: 2

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually
