Verified answer

{ xy = 7,4469
{ (x+2,54)*y = 7,4469 + 2,6162

{ y = 7,4469 : x
{ (x+2,54)*(7,4469:x) = 10,0631

7,4469x + 18,915126 = 10,0631x
2,6162x = 18,915126
x = 7,23                     
y = 7,4469 : 7,23 = 1,03

Ответ: {7,23; 1,03}, {1,03; 7,23}

Или так:
{ xy = 7,4469
{ (x+2,54)*y = 7,4469 + 2,6162

   xy + 2,54y = xy + 2,6162
     y = 2,6162 : 2,54
     y = 1,03                 x = 7,4469 : 1,03 = 7,23

Ответ: {7,23; 1,03}, {1,03; 7,23}
