Răspuns:
[tex]a + b + c = 296 \\ \\ a = b - 8 \\ \\ c = 10 \times a = > c = 10b - 80 \\ \\ b - 8 + b + 10b - 80 = 296[/tex]
[tex]12b - 88 = 296 \\ \\ 12b = 296 + 88 \\ \\ 12b = 384 \\ \\ b = 32 \\ \\ a = 32 - 8 = > a = 24 \\ \\ c = 10 \times 32 - 80 = > c = 240 \\ \\ a + b = 24 + 32 = > a + b = 56[/tex]
Verificare: 24 + 32 + 240 = 296 ( adevărat)
Răspuns:
296=a+b+c
296=b-8+b+10b-80
296=12b-88
384=12b
b=32
a=32-8=24
c=10*24=240
