Step-by-step explanation:

1) (-4 . x) + (-4 . 3) = 8
-4x - 12 = 8
-4x = 20
x = 20/-4
x = -5
2) 3 = (3/4 . b) + (3/4 . -8)
3 = 3/4b - 6
3 + 6 = 3/4b
9 : 3/4 = b
3 . 4 = b
12 = b
3) (1/6 . p) + (1/6 . 24) = 10
1/6p + 4 = 10
1/6p = 6
p = 36
4) 3/5 . a + 3/5 . 5,25 = 7,35
3/5a + 3,15 = 7,35
3/5a = 4,2
a = 7
