Question

Sistema de Ecuaciones 2x2

x + 5y =3

3x - 4y = -10

Answer 1

Respuesta:

x = -2 ; y = 1

Explicación paso a paso:

x + 5y =3

x = -5y + 3

Valor y

3x - 4y = -10

3 ( -5y + 3) - 4y = -10

-15y + 9 - 4y = -10

-15y - 4y = -10 - 9

-19y = -19

y = -19/-19

y = 1

Valor x

x + 5y =3

x + 5 * 1 = 3

x + 5 = 3

x = 3 - 5

x = -2

Comprobación

x + 5y =3

-2 + 5 * 1 = 3

-2 + 5 = 3

3 = 3 ✅✅

3x - 4y = -10

3 * -2 - 4 * 1 = -10

-6 - 4 = -10

-10 = -10 ✅✅
