Answer 2

Răspuns:

Explicație pas cu pas:

-

a)

(81-36-a) + (13+7)=53

(55-a)+20=53

55-a=53-20

55-a=33

a=55-33

a= 22

-

b)

(99-b-24)+12:2=16+50

(75-a)+6=66

75-a=66-6

75-a=60

a=75-60

a= 15

-

c)

(24:3+c):7= 4

(8+c)=4*7

8+c=28

c=28-8

c=20

-

d)

(36:6*d)-25 =5

(6*d)= 25+5

6*d=30

d=30:6

d= 5

-

e)

(e-30+50):5+32=42

(e-30+50):5=42-32

(e-30+50):5=10

(e-30+50)=5*10

(e-30+50)=50

e-30=50-50

e-30=0

e=0+30

e=30

-

f)

(96-12-40) +f -63=13

44+f=13+63

44+f=76

f=76-44

f= 32

-

g)

(23-18+g) +27-24:6=34

(5+g) +27-4=34

(5+g) +27=34+4

(5+g)+27=38

5+g= 38-27

5+g=11

g=11-5

g=6

-

h)

(27+9:h) +20:2-16=36

(27+9:h)+10-(12-8)=36

(27+9:h)+10-4=36

(27+9:h)+10=36+4

27+9:h+10=40

27+9:h=40-10

27+9:h=30

9:h=30-27

9:h=3

h=9:3

h=3
