Answer 1

1)a/../../
b/../../../+172000
422000-172000=25000
250000:5=50000
a=50000x2=100000
b=50000x3+172000
b=150000+172000=322000


2)a+b+c=183997
a/../../
b/../../../+1999
c/../../../../+1998
183997-1999-1998=180000
180000:9=20000
a=20000x2=40000
b=20000x3+1999
b=61999
c=20000x4+1998
c=80000+1998=81998


a-b=399750
a:b=6
a=6b
6b-b=5b
5b=399750
b=399750:5
b=79950
a=79950x6=47970
verificare
479700-79950=399750

Answer 2

a+b=422000
b=3(a/2)+172000

a+3(a/2)+172000=422000
5a/2+172000=422000
(5a+344000)/2=422000
5a+344000=844000
5a=500 000
a=500 000/5
a=100 000

b=3(a/2)+172000
b=3(100 000/2)+172000=3*50 000+172000=150000+172000=322000
VERIFICARE
a+b=422000
100 000 + 322 000=422 000


a+b+c=183997
3(a/2)+1999=b
2a+1998=c

a+3(a/2)+1999+2a+1998=183997
9a/2+3997=183997
(9a+7994)/2=2*183997
9a+7994=367994
9a=367994-7994
9a=360 000
a=360 000:9
a=40 000

3(a/2)+1999=b
2a+1998=c
b=3*(40000/2)+1999=3*20000+1999=60000+1999=61999
c=2*40000+1998=80000+1998=81998
Verificare
a+b+c=183997
40000+61999+81998=101999+81998=183997


a-b=399750
b=a/6
a-a/6=399750
5a/6=399750
5a=6*399750
5a=2398500
a=2398500:5
a=479700
