Question

cine ma.poate ajuta si pe.mn la aceste exercitii (65+18)-m=38; (15+68)=-c=100; ( 96-38)-a=77; (35-58)=n-7; (27+19)-b=26; (91-25)=d+28​

Answer 1

1. 83-m=38

-m=38-83

-m=-45 => m=45

2.83-c=100

-c=100-83

-c=17 => c=-17

3.58-a=77

-a=19=> a=-19

4. -23=n-7

n=-16

5.46-b=26

-b=26-46

-b=-20 => b=20

6. 66=d+28

d= 66-28 =38
