A+b+c=125
Notam cu x numarul:
a+x=46
b+x=61
c+x=66
Adunam cele trei relatii: a+x+b+x+c+x=46+61+66 
a+b+c+3x=173
a+b+c=125
Rezulta: 125+3x=173
3x=173-125
3x=48
x=48/3
x=16
Deci:
a+16=46 rezulta a=46-16=30
b+16=61 rezulta b=61-16=45
c+16=66 rezulta c=66-16=50

 a+b+c=125

a+x=46
a=46-x

b+x=61
b=61-x

c+x=66
c=66-x

46-x+61-x+66-x=125

173 -3x=125

-3x =125 -173

-3x= -48

x=16

a=46+16= 62

b=61+16=77

c=66+16=82
