Explicație pas cu pas:

a+b+c=178

a:b=4rest3

/__/__/__/__/__/__/__/__/a=4b+3

/__/__/b=2c+2

/__/c

a=b×4+3

(b*2):c=4 rest 4

2b=4c+4/:2

b=2c+2

Afla a,b,c

am reconstituit prin segmente

suma=4b+3+b+c=4(2c+2)+3+2c+2+c=

8c+8+3+2c+2+c=11c+13=178

11c=165

c=15

b=2c+2=32

a=4b+3=128+3=131

verificare 15+32+131=178
