Answer:

x = -2  ||   y = -3

Step-by-step explanation:

5x - 2y = -4

x + 2y = -8

--------------------------------------------

5x - 2y = -4

5x = -4 + 2y

x = (-4 + 2y)/5

x + 2y = -8

x = -8 - 2y

Solving simultaneously:

-8 - 2y  =   (-4 + 2y)/5

5(-8 - 2y) = -4 + 2y

-40 - 10y = -4 + 2y

-40 + 4 = 2y + 10y

-36 = 12y

y = -3

if y is -3 then x is:

x = -8 - 2y

x = -8 - 2(-3)

x = -2
