it is -15.4
they're both negative numbers (-7.7 and -7.7, when you look at them separately) and you just add them up, but keeping the - sign in front of the sum, because:
-7.7 - 7.7 = - (+7.7 + 7.7) = - (+15.4) = -15.4
(the minus in front of the parentheses changes all the signs within them, here applied twice)
