Question

Реши систему:
{x−y=0
x=$\frac{1}{4}$

Ответ: (
;
).

Answer 1

$\left \{ {{x-y=0} \atop {x=\frac{1}{4} }} \right.$

$\frac{1}{4}-y=0$

$y=\frac{1}{4}$

$(x,y)=(\frac{1}{4},\frac{1}{4} )$

$\left \{ {{\frac{1}{4}-\frac{1}{4} =0}\atop{\frac{1}{4} =\frac{1}{4} }} \right.$

$\left \{ {{0=0} \atop {\frac{1}{4} =\frac{1}{4} }} \right.$

ответ:   $(x,y)=(\frac{1}{4},\frac{1}{4} )$
