[(x + 6) / 2] + [(x - 9) / 5]

= [5(x + 6) / 10] + [2(x - 9) / 10]

= [(5x + 30) / 10] + [(2x - 18) / 10]

= (5x + 30 + 2x - 18) / 10

= (7x + 12) / 10

A question that has been shown incorrectly.
Will assume :-
[ x + 6 ] / 2 + [ x - 9 ] / 5

5x + 30 + 6x - 54
-----------------------------
10

11x - 24
---------------
10
