It looks like you've provided several mathematical expressions. It seems like you want me to simplify each of these expressions. I'll go through them one by one and simplify them for you:

a) -18n - 12n + 7.3n + 6.5n Combining like terms: -18n - 12n + 7.3n + 6.5n = -16.2n + 13.8n = -2.4n

b) -8x + 5.2a + 3x + 5a Combining like terms: -8x + 3x + 5.2a + 5a = -5x + 10.2a

d) 5a - 9.2m + 7a + 15m Combining like terms: 5a + 7a - 9.2m + 15m = 12a + 5.8m

v) 2/7x - 4/9y - 5/14x + 2/3y Combining like terms: (2/7x - 5/14x) + (-4/9y + 2/3y) = (4/14x - 5/14x) + (-4/9y + 6/9y) = -1/14x + 2/9y

g) -6a + 5a - x - 4x Combining like terms: -6a + 5a - x - 4x = -a - 5x
