X^2-xy=-2 y^2-xy=3 Решите систему Срочно !! Спасибо

Answer 1

Выразим y через х y=(x^2-2)/x  найдем х подставим згначение y во второе уравнение, заменин y на вырожение которое у нас получилось, получим x2-4+4/x^2-x2-2=3 х2 сократиться (х2 это х^2)  получим 4=9x2 x=+-(2/3) вычислим y gjkexftv y(2/3)=2/3-3=-2(1/3) и при y(-2/3)=-3(2/3)

Answer 2

Solving the System of Equations

To solve the system of equations x^2 - xy = -2 and y^2 - xy = 3, we can use the method of substitution or elimination. Let's proceed with the substitution method.

First, we solve one of the equations for one variable and then substitute that expression into the other equation.

Solving for x in terms of y

From the equation x^2 - xy = -2, we can solve for x in terms of y: x = (y^2 + 2) / y

Substituting x in the second equation

Now, we substitute the expression for x into the second equation y^2 - xy = 3: (y^2) - ((y^2 + 2) / y) = 3

Solving this equation will give us the value(s) of y, and then we can find the corresponding values of x.

Let's proceed with solving the equation to find the values of y.
