Answer:

[tex]x = - 11[/tex]

[tex]y = 19[/tex]

Step-by-step explanation:

[tex]x + y = 8 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ...1 \\

2x + y = -3 \: \: \: \: \: \: \: \: \: \: \: ...2[/tex]

from equation 1, we get

[tex]x = 8 - y

[/tex]

now put x = 8 - y in equation 2

[tex]

2(8 - y) + y= -3 \\ 16 - 2y + y = - 3 \\ - y = - 3 - 16 \\ - y = - 19 \\ y = 19[/tex]

now put y = 19 in equation 1

[tex]x + 19= 8 \\

x = 8 - 19 \\ x = - 11

[/tex]

thus, x = -11 and y = 19

X=-11
Y=19
If on a graph it would be {-2x-8[-20,20,-10,10]}
