Answer:

The answer is x = y = 10.

Step-by-step explanation:

It is given that, [tex]-4x + 8y = 40\\-x + 2y = 10\\x = 2y - 10[/tex].

Another equation is given by, [tex]-2x + y = -10\\y = 2x - 10[/tex].

Putting the value x = 2y - 10, in the second equation, we get [tex]y = 4y - 20 - 10\\3y = 30\\y = 10[/tex].

[tex]x = 2y - 10 = 20 - 10 = 10[/tex]
