Решите уравнение

1. 
   (128 + 49) - x = 28
   
2. 
   x - (133 + 75) = 32
   
3. 
   145 - (x + 45) = 50
   
4. 
   (39 + x) - 27 = 22
   
5. 
   500 – (120 – х) = 479-99
   
6. 
   220 + (х - 120) =997 -736
   
7. 
   472 – (z - 444) = 302
   
8. 
   6x + 131 = 437
   
9. 
   490 – y · 7 = 350
   
10. 
    k : 16 – 109 = 231
    
11. 
    8 · (х - 7) = 1080
    
12. 
    (k + 11): 23 = 27
    
13. 
    900 : (210 +х) =36
    
14. 
    40 + х : 70 = 54
    
15. 
    142 – (123 - х) + 14 =111
    
16. 
    67 – 36 : х = 55
    
17. 
    24 : (х +2) = 60 : 15
    
18. 
    17 + 6·(х - 5) = 47
    
19. 
    40 – 3 · (х + 2) = 10
    
20. 
    2 · (х - 12) +19 = 19
    
21. 
    63 : (2х - 1) = 21 : 3
    
22. 
    248 : (41 – 2х) = 8
    
23. 
    18 · (7х + 26) = 1854
    
24. 
    336:(5х+1)=6
    
25. 
    21· (5х+14)=2499
    

II. Решите уравнение (самостоятельно):

1. 
   55 – 8х = 7; 5) (60a - 30) : 5 = 18;
   
2. 
   27 : y + 29 = 38; 6) 92 + 56 : (14 - b) = 100;
   
3. 
   (t - 25): 20 = 9; 7) (c : 9) • 15 - 47 = 28;
   
4. 
   6 • (18 - k) = 54; 8) (410 – d): 7 + 70 = 120.
