The numbers 3 and 4 CAN NOT be in one line.

The numbers 2 and 3 CAN NOT be in one line.

It implies that 3 is in one line with the unknown number and 2 and 4 are in one line.

so 2 and 4 are in the second line.

Then 3 and X are in the first line, which implies that the unknown number is 9-3 = 6 in the first line.
