Question

(59xa+2023):50+2=2760

(b:5x501-1):1000=251

4160:65+c-1938=670

(1040:8+10870):11+2000-d=465

Answer 1

(59a+2023)/50=2758

59a+2023=17900

59a=135877

a=2303

b/5*501-1=251000

501b/5=251001

501b=1255005

b=2505

4160/65+c-1938=670

64+c-1938=670

-1874+c=670

c=670+1874

c=2544

(130+10870)/11+2000-d=465

11000/11+2000-d=465

1000+2000-d=465

3000-d=465

-d=-2535

d=2535
