Answer 2

(59×a+2023)÷50+2=
=2760
(59×a+2023)÷50=2670-2=
(59×a+2023)÷50=2758
(59×a+2023)=2758×50
(59×a+2023)=137900
59×a=137900-2030
59×a=135877
a=135877÷59
a=2303

(b÷5×501-1)÷1000=251
(b÷5×501-1)=1000×251
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
4160÷65+c=1938+670
4160÷65+c=2608
c=2608-65
c=2544

(1040÷8+10870)÷11+
+2000-d=465
(130+10870)÷11+2000=
=465+b
11000÷11+2000=465+b
1000+2000=465+b
b=3000 - 465
b=2535

a=2303
b= 2505
c=2544
d=2535
