(-4, -3)

Step-by-step explanation:

First divide the second equation by -1. It becomes y = -3x - 15.

Then, substitute this equation into the y of the first equation.

x + 2(-3x - 15) = -10

x - 6x - 30 = -10

-5x = 20

x = -4

Then substitute the x value into the equation x + 2y = -10

-4 + 2y = -10

2y = -6

y = -3
