Question

Реши уравнения. ( 30901 - а ) : 605 = 51.
39765 : ( b - 893 ) = 1205.

Answer 1

(30901- а) : 605 = 51
30901-а = 51•605
30901-а =30855
А= 30901-30855
А=46

Answer 2

(30901-а)÷605=51
30.901-a=51×605
30.901-a=30.855
a=30.901-30.855
a=46

39.765÷(b-893)=1205.
b-893=39.765÷1205
b-893=33
b=33+893
b=926
