Answer:

y=-3

x=2

Step-by-step explanation:

First substitute 2y+8 for x in the equation: 2x-5y=19.

2(2y+8)-5y=19

4y+16-5y=19

    -16       -16

4y-5y=3

Combine.

-y=3

Divide.

y=-3

Then, substitute -3 for y in the equation 2y+8, because x=2y+8.

x=2(-3)+8

x=-6+8

x=2

Should be correct! (Unless I made a simple math mistake.)
