Question

ce valoare au cele trei necunoscute? a:b=3 rest 12 c:b=4. a+b+c=104300

Answer 1

a:b=3(r12)⇒a=3b+12
c:b=4⇒c=4b
a+b+c=104300
3b+12+b+4b=104300
8b+12=104300
8b=104288
b=104288:8
b=13036
a=3·13036+12
a=39108+12
a=39120
c=4·13036
c=52144
Verificare: a+b+c= 39120+13036+52144= 52156+52144=104300
