Answer:

[tex]\boxed{x = -5~~and~~ y =1}[/tex]

Step-by-step explanation:

-5x - 10y = 15

-3x + 10y = 25 +

-8x = 40

[tex]x = \frac{40}{-8}[/tex]

x = -5

.

Substitute the value of x to one of equations

-5(-5) - 10y = 15

25 - 10y = 15

-10y = 15 - 25

-10y = -10

[tex]y = \frac{-10}{-10}[/tex]

y = 1
