Answer:

(5, -2)

Explanation:

6x + 10y = 10 You add the two equations together

-6x - 24 y = 18

-14y = 28 Divide both sides by -14

y = -2

Substitute -2 for y into either of the two equations above or the two original equations. I am going to choice

3x + 5y = 5

3x + 5(-2) = 5

3x -10 = 5 Add 10 to both sides

3x - 10 + 10 = 5 + 10

3x = 15 Divide both sides by 3

x = 5

Check:

3x + 5y = 5

3(5) + 5(-2) = 5

15 - 10 = 5

5 = 5 Checks

-2x - 8y = 6

-2(5) - 8(-2) = 6

-10 + 16 = 6

6 = 6 Checks
