    This question may have more than one solution according to  the different logic.

    1) Sum of the rows –
    Sum of rows is 17 in each case.
    3+6+8=17
    5+8+4=17
    4+7+ x=17
    Thus X=6

    2)Sum of columns –
    Sum of columns is increasing by 9.
    3+5+4=12
    6+8+7=21(12+9)
    8+4+x=30(12+18)
    Thus X=18

    3)Average of first two numbers in columns –
    Average of first two = third.
    (5+3)/2=4
    (6+8)/2=7
    (8+4)/2=6
    Thus X=6

    I would like go with X=6. (Higher probability)
