some help please.

i reached to the following :

=CHOOSE(MATCH("X";F7;0);5) which means if cell f7 has x
give me exactly 5

=CHOOSE(MATCH("y";F8;0);6) which means if cell f8 has y
give me exactly 6

MY QUESTION NOW.....IS IT POSSIBLE TO COMBINE THOSE TWO FORMULAS IN JUST
ONE ??? . ( I WANT IT SIMILAR TO [ IF(AND( ] FUNCTION )
