Answer 2

Ответ:

$\mathbf {x_{1}=2, \quad v_{1}=-3};$

$\mathbf {x_{2}=3, \quad v_{2}=-2};$

Объяснение:

$\left \{ {{x^{2}+v^{2}=13} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{x^{2}+(x-5)^{2}=13} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{x^{2}+x^{2}-10x+25-13=0} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{2x^{2}-10x+12=0} \atop {v=x-5}} \right. \Leftrightarrow$

$\Leftrightarrow \left \{ {{x^{2}-5x+6=0} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{(x-2)(x-3)=0} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{x-2=0} \atop {v=x-5}} \right. \quad \vee \quad \left \{ {{x-3=0} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{x=2} \atop {v=x-5}} \right. \quad \vee$

$\vee \quad \left \{ {{x=3} \atop {v=x-5}} \right. \Leftrightarrow \left \{ {{x=2} \atop {v=-3}} \right. \quad \vee \quad \left \{ {{x=3} \atop {v=-2}} \right. ;$
