Answer 1

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

(b:5·501-1):1000=251
b:5·501-1=251·1000
b:5·501-1=251000
b:5·501=251000+1
b:5·501=251001
b:5=251001:501
b:5=501
b=501·5
b=2505

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