Question

Rezolva:
(59xa+2023):50+2=2760
(b:5x501-1):100=251
4160:65+c-1938=670

Answer 1

(59xa+2023):50+2=2760
(59xa+2023):50=2760-2
(59xa+2023):50=2758
(59xa+2023)=2758·50
59xa+2023=137900
59xa=137900-2023
59xa=135877
a=135877:59
a=2303

(b:5x501-1):100=251
(b:2505-1)=251·100
 b:2505-1=25100
b:2505=25100+1
b:2505=25101
b=25101×2505
b=62878005

4160:65+c-1938=670
64+c=670+1938
64+c=2608
c=2608- 64
c=2544

Answer 2

(59a + 2023) : 50 = 2760 - 2
59a + 2023 = 2758 * 50 
59a = 137 900 - 2023
a = 135 877 : 59
a = 2303

(b : 5 * 501 - 1) = 251 * 100
b : 5 * 501 - 1 = 25 100
b : 5 * 501 = 25 100 + 1
b : 5 = 25 101 : 501
b = 50,10 * 5
b = 250,50

64 + c = 670 + 1938
c = 2608 - 64
c = 2544
