A + b = 746
a + 102 = b - 104 => a = b - 104 - 102 => a = b - 206
Din a + b = 746 => (b-206) + b = 746 => b - 206 + b = 746 => 2b - 206 = 746 =>
   => 2b = 746 + 206 => 2b = 952 => b = 476 => a = 476 - 206 => a = 270

X+y=746
x+102=y-104
102+104=y-x
y-x=206⇒y=206+x
x+206+x=746
2x=746-206
2x=540⇒x=540/2=270
x=270
270+y=746⇒y=746-270=476
y=476
Sper ca te-am ajutat!!!:)
