1) 15-4 (d+3) = - 17

15-4d+12 = - 17

4d = 15+12+17

4d = 44

d = 44/4

d = 11

2) c-24 = 2c-18

-24+18 = 2c-c

c = - 6

3) 3 (n-3) + 22 = 28

3n-9+22 = 28

3n = 28-22+9

3n = 15

n = 15/3

n = 5

4) 0.1x+1.2 = 2.3

0.1x = 2.3-1.2

0.1x = 1.1

x = 1.1/0.1

x = 11

5) - 8x-8 = 34-x

-8-34 = 8x-x

7x = - 42

x = - 42/7

x = - 6
