Question

Ma poate ajuta cineva cu urmatorul simtem : y-x= 1 ; 5x+y =6

Answer 1

$\left \{ {{y-x=1} \atop {5x+y=6}} \right.$⇒$\left \{ {{y=x+1} \atop {5x+x+1=6}} \right.$⇒ $\left \{ {{y=x+1} \atop {6x=5}} \right.$ ⇒ $\left \{ {{y= \frac{5}{6} +1} \atop {x= \frac{5}{6} }} \right.$ ⇒ $\left \{ {{x= \frac{5}{6} } \atop {y= \frac{11}{6} }} \right.$

Sper ca te-am ajutat.
