Question

Cine ma ajuta si pe mine ? va rog frumos

Answer 1

22-a=17
-a= 17-22
-a=-5/(-1)
a=5


27+b=63
b=63-27
b=36


restul sunt la fel

Answer 2

15. 22- a=17
22-17=5
a=5

27+b=63
63-27=36
b=36

19+c=47
47-19=28
c=28

73- d=26
73-26=47
d=47

e+31=60
60-31=29
e=29

f-74=6
74+6=80
f=80

g-26=36
26+36=62
g=62

h+18=99
99-18=81
h=81

i+(39+19)=61
i+58=61
i=61-59
i=2

(91-10)-j=53
81-j=53
j=81-53
j=28

k-(38-19)=27
k-19=27
k=27+19
k=46

(30-8)+l=68
22+l=68
l=68-22
l=46
