Answer:
3) 3a - 2 + 3 = -2
3a = -2 + 2 - 3 = -3
a = -3/3 = -1
4) m/-6 - 18 - 4 = -16
m/-6 = -16 + 18 + 4 = 6
m = 6 · (-6) = -36
5) x/-2 - 4 + 22 = -28
x/-2 = -28 + 4 - 22 = -46
x = -46 · (-2) = 92
6) -13 = 5 + 20m - 2m
-13 = 5 + 18m
-18 = 18m
m = -18/18 = -1
7) -2(2p - 1) = -14
-4p + 2 = -14
-4p = -14 - 2 = -16
p = -16/(-4) = 4
8) -1(8x + 20) = 12
-8x - 20 = 12
-8x = 12 + 20 = 32
x = 32/(-8) = -4
9) -49 = 7(2x + 3)
-49 = 14x + 21
-14x = 49 + 21 = 70
x = 70/-14 = -5
10) 3(8h - 4) + 17 = -19
24h - 12 + 17 = -19
24h = -19 + 12 - 17 = -24
h = -24/24 = -1
