Question

1) 23+(x+18)=92-17
2) 80-(62-y)=24+19

Answer 1

Ответ:

1). 23+(x+18)=92-17

23+(x+18)=75

x+18=75-23

x+18=52

x=52-18

x=34

Answer 2

Ответ:

23+(x+18)=75

x+18=75-23

x+18=52

x=52-18

x=34

23+(34+18)=92-17

80-(62-y)=24+19

80-(62-y)=43

62-y=80-43

62-y=37

y=62-37

y=25

80-(62-25)=24+19
