Question

a+b+c=232 ,a:b=14r5 ,b:c=7r1. determinati numerele

Answer 1

a+b+c=232 
a=14b+5 
b=7c+1 
a=14(7c+1)+5 
a=98c+14+5 
a=98c+19 Inlocuim pe b si pe a 
98c+19+7c+1+c=232 
106c+20=232 
106c=232-20
106c=212
c=2
b=7*2+1
b=15
a=98*2+19
a=215
a+b+c=215+15+2=232

Answer 2

a+b+c = 232
a = 14b+ 5 = 14(7c+1) + 5 = 98c + 19
b = 7c+1 
98c + 19 +7c + 1+ c = 232
106c = 212   c = 2    a = 215     b = 15
