-5x-10y=15
-5x+10y=15

x = -3

y = 0

Step-by-step explanation:

-5x-10y=15  >(equation 1)

-5x+10y=15>(equation 2)

Add (equation 1) and (equation 2)

(-5x-10y) + (-5x+10y) =15 + 15

-5x-10y - 5x + 10y = 30

-5x -5x -10y + 10y = 30

- 10x = 30

x = 30/- 10

x = -3

put x = -3 in (equation 1)

-5(-3) - 10y=15

15 -10y = 15

-10y = 15 - 15

-10y = 0

y = 0/ -10

y = 0

(-3,0)

Step-by-step explanation:

-5x-10y=15

-5x+10y=15

Add the two equations together to eliminate y

-5x-10y=15

-5x+10y=15

-10x  = 30

Divide each side by -10

10x/-10 = 30/-10

x = -3

Now we need to find y

-5x +10y = 15

-5(-3) +10y = 15

15 +10y = 15

Subtract 15 from each side

15-15 +10y = 15-15

10y =0

Divide each side by 10

10y/10 = 0/10

y=0

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
