1)

t + 7 = 12

subtract 7 from both sides:

t = 5

2)

h - 3 = 8

add 3 to each side:

h = 11

3)

8 = b - 9

add 9 to both sides:

b = 17

4)

k - 4 = -14

add 4 to both sides:

k = -10

5)

m + 9 = -7

subtract 9 from both sides:

m = -16

6)

y - 10 = -3

add 10 to both sides:

y = 7

7)

-14 = 2 + d

subtract 2 from both sides:

d = -16

8)

15 + n = 10

subtract 15 from both sides:

n = -5

9)

-8 = r - 6

add 6 to both sides:

r = -2

10)

11 = w - 5

add 5 to both sides:

w = 16

11)

-9 = g + 9

subtract 9 from both sides:

g = -18

12)

12 + c = 16

subtract 12 from both sides:

c = 4

13)

r + s = 180

14)

1996 - 23 = 1973

Then the inhabitants of Africa is 4x (4 cases Greece). Africa's inhabitants is given, that's 40 4 mil. So, 4x = 40 4, x = 40 4/4, x = 11. X is Greece's inhabitants so this is 11 million.
