Question

a:b=5 rest 24
C=a:2
a+b+C=257
a=? b=?

Answer 1

A:b=5 rest 24⇒a=5×b+24
C=a:2⇒c=a/2=(5b+24)/2
a+b+C=257
a=? b=?
(5b+24)+b+(5b+24)/2=257
(5b+24+b)×2+(5b+24)=514
(6b+24)×2+5b+24=514
12b+48+5b+24=514
17b=514-72
17b=442
b=26
a=5×b+24=154
a=154
c=a/2=154/2=77
c=77
verificare
a+b+c=257
154+26+77=257
257=257
a=154,  b=26,  c=77
