Решить примеры 1) 15-4(d+3)=-17. 2) c-24=2c-18. 3) 3(n-3)+22=28. 4) 0.1x+1.2=2.3. 5) -8x-8=34-x.

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
