34kurt

Answer:

$x = - \frac{2}{3} \: \: \: y = \frac{14}{3}$

Step-by-step explanation:

Since we know -7x=y we use the substitution method and plug it in the top equation.

$x + - 7x = 4$

$- 6x = 4$

$x = - \frac{4}{6}$

or x=-2/3

Then plug it back in the the bottom equation

$- 7( \frac { - 2}{3} ) = y$

y=14/3
