Question

{2(x+5=4(y-4x).........(1)
{10(y-x)=11y-2x..........(2)

Answer 1

Respuesta:

$(x, y) = (-\frac{7}{11}, -\frac{4}{11} )$

Explicación paso a paso:

2(x+5)=4(y-4x).........(1)

10(y-x)=11y-2x..........(2)

.

x=(2/9)y -(5/9)

10(x-y)=11y-2x

.

10((2/9)y -(5/9) -y) = 11y - 2 ((2/9)y -(5/9))

y = - (4/11)

.

x=(2/9)( - 4/11) - (5/9)

x = - (7/11)
