{ 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}
