Answer 2

23.
a+b=422000
b=3a+172000
a+3a+172000=422000
4a=422000-172000
4a=250000
a=250000/4
a=62500
b=422000-62500=359500

24)
a+b+c=183997
3*a/2+1999=b
2a+1998=c
a+3a/2+1999+2a+1998=183997
a+3a/2+2a=183997-1998-1999
3+3a/2=180000
6a+3a=360000
9a=360000
a=40000
b=3*a/2+1999=3*40000/2+1998=61999
c=2a+1998=2*40000+1998=81998

25.
a-b=399750
a=6b
6b-b=399750
5b=399750
b=79950
a=79950*6=479700
