Question

Помогите пожалуйста!

Answer 1

y - 5x = - 8 
y - x^2 = - 2 

y = 5x - 8 
5x - 8 - x^2 + 2 = 0 * 

*
- x^2 + 5x - 6 = 0  // : (-1)
x^2 - 5x + 6 = 0 
D = 25 - 24 = 1 
x₁ = ( 5 + 1)/2 = 6/2 = 3;
x₂ = ( 5 - 1)/2 = 4/2 = 2;

x₁ = 3 
y₁ = 5*3 - 8 = 7;

x₂ = 2
y₂ = 5*2 - 8 = 2

Ответ:
( 3; 7) ; (2; 2)
