Question

4x-7y=8
5x-7y=10

Ayuda

Answer 1

Respuesta:

x = 2

y = 0

Explicación paso a paso:

$\boxed{\left \{ {{4x-7y=8} \atop {5x-7y=10}} \right. }$

4x - 7y = 8

5x - 7y = 10

-x - 0 = -2

-x = -2

x = -2/-1

x = 2

Reemplazamos para hallar y

4x - 7y = 8

4(2) - 7y = 8

8 - 7y = 8

-7y = 8 - 8

-7y = 0

y = 0/-7

y = 0

$\boxed{\left \{ {{x=2} \atop {y=0}} \right. }$
